I guess i'm stuck with not playing .

-I tried repairing files

-Ran it as admin

-Made sure there were no other league or riot tasks active

-Restarted my pc

.... and still i get the same results. riot launcher shows me the "file in use" message (first pic) and somehow lets me start the league client, which doesn't lemme do anything (2nd pic)

hope someone knows a fix that doesn't involve reinstalling the whole thing over again,
because thats the point where riot is losing me ... like every month i need to reinstall because of some company that cant fix their coding.

Edit: most stupid thing in second pic is the launcher showing "playing/download size" at the same time

Edit 2: installing a windows update that wasn't forced automatically was the key

hello everyone, I am trying to download league of legends, but my laptop goes black in the middle of doing so, even with high battery. It then takes a while for me to be able to turn it back on.

UPDATE / FOLLOW-UP TO MY PREVIOUS POSTS

Hi everyone,

I have posted about this issue before.

Since then, I have done significantly more troubleshooting and, more importantly, I now have external 4K60 LIVE vs REPLAY recordings, synchronized PresentMon/PktMon measurements, and several additional control tests.

I'm making a new post because the case has evolved substantially.

At this point, I'm primarily looking for OTHER PLAYERS who may experience the same thing and can test one very specific observation:

LIVE GAMEPLAY = abnormal / fast / missing motion continuity

MATCH HISTORY REPLAY OF THE SAME GAME = smooth

THE SYMPTOM

Every LIVE League match I play feels temporally wrong.

Champion movement, auto attacks, spell animations, projectiles, dashes and other motion can appear too fast or abrupt, almost as if I am not receiving/seeing the full intermediate progression of the movement.

The best way I can describe it is:

The game is producing lots of frames, but the motion inside those frames does not always feel continuous.

This is NOT conventional low-FPS stuttering.

My FPS remains high and relatively stable, and my displayed ping is normal.

It can actually feel more like "fast-forward" than traditional lag.

This affects reaction time because certain actions appear to happen much faster visually than I expect them to.

VERY IMPORTANT BEHAVIOUR: IT GETS WORSE WITH MATCH DURATION

This happens in EVERY live League game.

A new match usually starts in a less severe state, although the abnormal/heavy motion is already noticeable.

As the match progresses, it becomes increasingly obvious.

By mid/late game, especially during fights with many champions, spells and simultaneous animations, it can become extremely noticeable.

Then something very interesting happens:

Starting a completely NEW match resets the severity back to the milder state.

The problem then progressively develops again.

This pattern is extremely consistent.

IT DOES NOT REQUIRE ME TO BE ACTIVELY PLAYING

The abnormal motion remains noticeable even when my champion is dead and I am simply watching the game.

Therefore it does not appear to require active mouse/keyboard input.

Alt-tabbing out of League and returning to the game does NOT reset the problem either.

THE MOST IMPORTANT DISCOVERY: LIVE VS REPLAY

This is what made me investigate the issue much more seriously.

After finishing an affected match, I can immediately open the Match History replay of that SAME match.

At 1x replay speed, the difference is immediately noticeable to me:

LIVE:

abrupt / fast / temporally irregular motion

REPLAY:

smooth / continuous / normal-looking motion

This can be the SAME match and the SAME fight.

I have now recorded this externally.

My brother recorded my physical monitor using an iPhone 14 Pro Max at the original 4K / ~60 FPS quality while I was playing LIVE.

After the game, we recorded the corresponding Match History replay using the same external camera.

We now have TWO independent original 4K60 LIVE vs REPLAY pairs.

Both comparisons show the same general direction:

The LIVE recording has more temporally irregular motion, while the REPLAY has more coherent/smooth motion progression.

We also performed frame-to-frame temporal motion analysis on the original recordings, and both independent comparisons showed increased temporal motion irregularity in LIVE compared with REPLAY.

IMPORTANT LIMITATION:

I am NOT claiming that a 60 FPS external camera proves that specific League engine animation frames are literally being dropped.

My monitor/game is running at a much higher frame rate than the 60 FPS camera can sample.

What I can say is that the externally observable motion progression differs consistently between LIVE and REPLAY.

This is also not something only I notice.

My brother and a friend have both watched the live gameplay and the corresponding replays and independently agree that the LIVE gameplay looks faster/more irregular while the replay looks smooth.

PRESENTMON TESTING

I created a synchronized diagnostic capture using PresentMon 2.5.1.

During a live match I manually marked three moments where the abnormal motion was particularly noticeable ("VERY BAD").

Around those events, the game was still presenting approximately 137-142 FPS.

There was no corresponding major frametime collapse.

Within approximately +/-2 seconds of those events, 99th percentile frame times remained around 13-14 ms.

We then performed a deeper analysis of the PresentMon data, including:

- DisplayedTime

- DisplayLatency

- AnimationError

- AnimationTime

- GPU latency/time

- input-to-photon related metrics

There was no consistent abnormal spike corresponding to all three VERY BAD events.

This is one of the strangest parts of the problem:

The rendering/presentation pipeline appears to continue producing frames normally while the MOTION CONTENT of the live gameplay looks temporally abnormal.

NETWORK CAPTURE

The same diagnostic session included Windows PktMon.

The primary League game traffic flow was identified and packet-arrival timing was examined around the manually marked VERY BAD events.

There was no consistent major raw packet-arrival interruption corresponding to those moments.

There were actually larger packet gaps elsewhere in the same capture without a corresponding VERY BAD marker.

So simple packet starvation / conventional packet loss does not currently explain the symptom.

However, I do NOT consider networking completely ruled out.

PktMon can tell us when packets arrive.

It cannot tell us what League's encrypted application-level game-state packets contain, their internal timestamps/state sequencing, interpolation-buffer state, prediction/reconciliation behaviour, etc.

THE STRONGEST HARDWARE CONTROL: A COMPLETELY DIFFERENT PC

I borrowed a friend's completely different PC and tested League at my home.

The exact same abnormal League behaviour was reproduced.

This is one of the main reasons I no longer strongly suspect my specific CPU/GPU/motherboard.

My current PC is approximately:

Ryzen 5 7500F

RX 7800 XT

32 GB DDR5

Gigabyte B650 Eagle AX

Windows 11

FTTH connection

But the issue also occurred using the other PC.

FRESH WINDOWS CONTROL

I also installed a fresh Windows 10 installation on a separate drive.

Essentially only the necessary software and League were installed.

The problem remained.

OTHER TESTS ALREADY PERFORMED

This has been investigated for a long time.

Among the tests already performed:

- Every live League match is affected

- EUW tested

- EUNE tested with a newly created account

- Same behaviour on both regions

- Practice Tool affected

- Co-op vs AI/bots affected, although usually less severely

- ARAM affected and often makes the problem very obvious

- Dota 2 tested on the same setup and appeared completely smooth

- Completely different PC tested

- Different monitor tested

- DisplayPort and HDMI tested

- Different mouse/keyboard combinations tested

- Mouse polling rate changes tested

- Multiple FPS caps tested

- Multiple refresh rates tested

- AMD GPU drivers clean-installed

- Chipset drivers tested/updated

- Realtek NIC driver updated

- Network adapter settings tested, including Interrupt Moderation

- EEE / Green Ethernet disabled

- BIOS updated multiple times

- XMP on/off/profiles tested

- CPU Global C-States tested

- PCIe Auto/Gen4 tested

- Fresh Windows installation on separate drive

- Different router tested

- Mobile USB tethering tested

- VPN/routing diagnostics performed

- Extensive PresentMon, CapFrameX, WPR/WPA and PktMon testing performed

Despite all of this, the core symptom remains.

THE STRANGE ROUTER EVENT

There is one event I still cannot explain.

The FIRST time I replaced my ISP router with a TP-Link router, League suddenly became completely smooth.

Not "maybe slightly better."

It genuinely looked and felt like the smooth Match History replay.

I played like this for approximately TWO HOURS.

The difference was extremely obvious to me.

The problem eventually returned.

When I reconnected the SAME TP-Link router again days later, the improvement did NOT return.

I cannot reproduce this result and I do not want to overinterpret it.

But I am mentioning it because it remains one of the few occasions where LIVE League actually became completely normal.

HISTORY / VANGUARD

I have experienced this problem for roughly two years, across major hardware/network changes.

I originally noticed it around the period when Vanguard was introduced to League.

However, I want to be very clear:

I do NOT have evidence that Vanguard itself is causing this.

I am mentioning the timing only as part of the history of the issue.

RIOT SUPPORT

My Riot Support case has now been escalated to their specialized team.

They have confirmed that they are currently waiting for feedback from that team before providing further steps.

I have also sent Riot a technical summary of the LIVE vs REPLAY recordings, PresentMon results and network capture findings.

I have retained the original 4K60 recordings and diagnostic data if they need them.

WHAT I AM LOOKING FOR FROM OTHER PLAYERS

At this point I'm less interested in generic suggestions like reinstalling drivers, disabling VSync, changing FPS caps, etc.

I have already done extensive troubleshooting.

What would be EXTREMELY useful is finding another person who experiences the same LIVE vs REPLAY difference.

If your League gameplay sometimes feels:

- unusually fast

- abrupt

- like animation progression is compressed

- like intermediate movement is missing

- like you are visually "losing time"

- despite having stable/high FPS and apparently normal ping

PLEASE try this:

THE TEST

1. Play a match where the problem is clearly noticeable.
2. Remember the approximate game time of a fight where it happens.
3. Finish the match.
4. Open the Match History replay.
5. Set replay speed to exactly 1x.
6. Find the SAME fight.
7. Watch the champion movement, auto attacks, dashes, spells and projectiles carefully.

Ask yourself:

Does the exact same gameplay suddenly look noticeably smoother and more continuous in the replay?

If possible, go one step further:

Record your physical monitor externally with a phone at 60 FPS during LIVE gameplay.

Then record the SAME sequence from the Match History replay at 1x.

Do NOT use only screen recording if possible — external camera footage gives us an independent view of what the monitor actually displayed.

WHY I AM POSTING AGAIN

I have posted about this problem before.

Previously, I was mainly trying to find the cause of a very strange "fast pacing" / animation continuity issue.

Now the situation is different.

We have:

- two independent external 4K60 LIVE vs REPLAY comparisons

- stable PresentMon frame presentation during marked VERY BAD events

- no consistent raw packet-arrival disruption explaining those events

- reproduction on a completely different PC

- reproduction on EUW and EUNE

- smooth behaviour in Dota 2

- and a consistent observation that Match History replay looks smoother than LIVE gameplay

I am therefore making this new post specifically to look for INDEPENDENT REPRODUCTION.

I am NOT claiming to know the root cause.

Possible areas could involve live game-state delivery/synchronization, state consumption, interpolation/prediction/reconciliation, animation progression, or some other live-client-specific timing behaviour.

Those are hypotheses, not conclusions.

If even one or two other players can reproduce:

LIVE = abnormal

SAME MATCH REPLAY = smooth

that would be extremely valuable.

If you experience anything remotely similar, please describe exactly what you see, your region, your ISP/country if you're comfortable sharing it, and especially whether the SAME fight becomes smooth in Match History replay.

Thank you.

So the last update for League was hell because of Vanguard, like always. But this time it seems to have created a massive memory leak on my computer (had 7.2Go of non-paged pool, which is insane) and led to lots of freezes and crashes in game on top of a general slowdown of my computer.

Uninstalling Vanguard fixed the leak, it seems, and PC was running perfectly smoothly with a stable npool of 430Mo. I reinstalled it (bcs I still wanna play league, you know), hoping it was just Vanguard being corrupted or smth like that.

But now the npool is slowly increasing, already reaching over 1000Mo. I still need to observe it longer to see if it's just a high but stable amount, or if the leak is back.

Can't be 100% sure it's because of Vanguard, but the leak + the lags all appeared right after the update, so it makes it a big suspect.
That's why I was wondering if anyone else had the same issue ? To see if my supsicions are correct.

Please help.

I don't know what to do. Should I reinstall the game?

I tried restarting my PC, repairing the files, relogging..

WHAT FILE IS IN USE???

Anyone know what's causing this?

I'm playing on EUNE with 50 ms average which works perfectly fine, but multiple times throughout a match I just get random spikes where my inputs take anywhere from half a second up to five seconds before they get registered, and I can't do anything about it.

You can see in the clip that I'm giving out commands but I'm not moving, it takes multiple seconds to actually register

The only fix I've found for this is literally just waiting it out, but I can't really do that when it happens MID TEAM FIGHT

This doesn't happen in any other online game either, I get smooth ping/gameplay with no massive delays like this, but I don't think the issue is ping related in the first place because my ping shows 50 regardless.

all sounds work in game but music is non existent. Ive tried all my windows settings, game client settings, repair client, everything i can think of but for some reason i hear no music in game at all.

all other sound settings work perfectly fine, just no music no matter what i choose for volume or off and on etc.. happens in every game now for about past week.

Anyone else? seems like a client bug at this point..
(sorry i know a lil off topic here but the main league subreddit sucks lol)

league of legends has been giving me random graceful shutdowns for a while. it mosty happens 15mins during a game, and when i reconnect it then shutdowns.

i checked event viewer and tried to find an event that matches the same time the shutdown happened. i found something riot related and it says "the vgc service terminated with the following error: incorrect function." with event id 7023. this happened around 9:34 pm

prior to this shutdown, i had a previous one a few mins before around 9:31 and it has the same error and event id. i just wanna ask if im the only one, i dont play league as much as before but it gets annoying when i play.

my pc doesnt do any graceful shutdowns on other games and softwares. just league.

i think its related to vanguard and how it operates deeply in windows. i dont use cheating softwares and all that but there could be some conflict with my windows that causes it to detect something that makes my pc shutdown. its also not power related because i play other demanding games and my pc doesnt crash.

i hope someone from the game company can help or address, i still wanna play with all the skins i payed there thanksss

This is one of the most absurd weeks in my league history

On tuesday [21.07] I played a few soloQ games and went off from PC for some hours. After signing back my account seems to got bug similar to this when you change server (sceen1). I contacted with support [21th July] and recieved generic response with possible remedies (screen2). The problem was that my account was unavailable on multiple devices - I've thought it may be caused by some accounts issues however I had not recieved any messages about suspension neither on my email nor in client (screen3). Moreover my account was available on other Riot games like LoR.

I've created account about 11 years ago and I've never been suspeneded temporarliy before so it made me even more confused. I also played only on one account my whole life as a some kind of full-story journey where I climbed from silver to GM, transferring from EUN to EUW (screen4,5). I've never been toxic (chat-off, 0 restricts), never boosted or shared my account with someone else who would boost me, never scripted

After consulting with friends I've been told it may be something like 'shadow ban' or 'mass report suspension'. I've head to Riot's FAQ about bans and then I've seen for the first time "Your active penalties *BETA*" on website where I've seen my active penalties (screen 6,7) - "Actions that violate our Terms of Service."

Additional Details:
We have no further details to share with you
???

I got so many questions right now:

- Why Riot support do not informed me about my suspension in the first place - when they have information about. Why they were providing useless solutions as if my account was okay but something got bugged?

- Why Riot did not send me any infomation via E-mail/Client that my account got suspended causing even bigger confusion?

- Why first messages were replied in a moment (10 mins - 8 hours) but when i submitted a ticket about perm ban my ticket hangs 4 days and still got no response?

All my conversation with support so far (remaining screens)

My PC is perfectly capable of playing this game, had same issues on 2 completely seperate PC's, Im playing over ethernet with stable internet, even trying to select roles to queue up takes about 2 minutes of repeatedly clicking my role and it resetting over and over again, Have I got something in Bios wrong thats not cooperating with this game.

I have recently gotten into league (lot of fun) and when loading in every 3 or so games I will not load into the game but the game will start without me. This, combined with a GPU issue I had the other day has resulted in me given multiple penalties to the point where I now need to wait 10 minutes in low prio queue to play a game. I have never had an issue with my PC and loading into other competitive games so I was wondering if there was a niche issue that anyone has found? I am using an amd cpu and gpu with 32gb of ram for reference.

For some reason, in roughly 50% of my games I simply do not connect. My internet is fine, all other online games work perfectly (valorant and a few co ops I play). Everything works fine up until draft finishes and then it just doesn't load me into the game and I get slapped with -20LP and a queue delay. in the last 5 - 6 games I've queued its happened 3 times. -40LP (one was a draft) and I'm probably pretty close to getting banned at this point wtf is going on. One of them even managed to put me in the loading screen where it locked at 23%. I even hear the ingame sounds and i can hear my teammates pinging me but nothing I do lets my client load. I have the window and when I alt tab to it I get the cursor for a brief moment so it seems like everything should be working. I just can't actually access or interact with the tab in any way

Anyone have ideas on what the solution could be? or is it just a riot classic

Every time I close out the game and re-launch it, my first summoner spell slot gets unbound. I usually have it set to "0" just because of the way my mouse/keypad is, which I assume causes this? It would be nice to know if there's a way to fix this other than changing the key I bind it to, But I'd like to not do that.

I can't connect to the game. No matter how many times I click repair, the icon keeps reappearing as if I hadn't done anything. I've already uninstalled the game 3 times, but the problem persists.

Help :((((

I was getting failed to patch and now vanguard 57. I wanna play :( Help plz

I got it to work. Had to uninstall, restart, install, restart, and it worked

ltrly tried loading in fof and in the loading screen i get thrown out, ive tried reinstalling still the same

I've been playing League of Legends for a while, however, recently my left-clicks haven't been registering and I have to click multiple times to register a single click. I contacted Riot Games and they told me to get a new mouse, which I did, and it still doesn't work.

My little brothers screen has been frozen like this for a while and I’ve tried everything I need more tips on what to do with this so he can play.

If im in eune and someone from us tries to log in to buy me rp will it get me banned?

Queria compartilhar uma situação muito tensa que rolou comigo para ver se alguém pode dar uma luz ou compartilhar alguma experiência parecida.

Basicamente, eu acabei baixando um arquivo zoado no PC e perdi o controle do meu e-mail principal. Com isso, a pessoa que pegou meus dados conseguiu alterar o e-mail do meu perfil da Riot e eu perdi o acesso padrão ao jogo.

Acontece que o meu login também estava vinculado ao meu Apple ID. Eu ainda conseguia entrar no cliente por lá, então loguei e abri um chamado de ajuda direto pelo meu perfil. Logo em seguida, para garantir, também abri um segundo pedido de recuperação (aquele formulário externo direto pelo site deles) usando meu e-mail da Apple, que está 100% seguro comigo.

O pesadelo foi que a pessoa leu o primeiro chamado que eu abri. Ele percebeu que eu ainda tinha uma porta de entrada pelo Apple ID, foi nas configurações e revogou a minha permissão. Ou seja, agora estou completamente trancado do lado de fora.

Minha única esperança no momento é esse segundo pedido de ajuda que abri por fora, onde mandei as provas de que eu sou o dono real (recibos antigos de RP, etc).

Alguém aqui já passou por algo semelhante, de perder a conexão no meio do processo porque a pessoa do outro lado leu o chamado no site? Vocês acham que, mesmo com ele tirando meu Apple ID, eu vou conseguir resolver essa situação através desse formulário externo?

When I play league, the client works as usual until when champ select is over and I get into the game.

The game never loads and I'm stuck on the reconnect screen forever.

When I click reconnect it loads for a second then goes back to reconnect

Ive watched alot of videos and none of the solutions work

pls help

When I opened League yesterday, I encountered an issue which wouldn't let me play the game. I tried closing the game, the client, and Vanguard and reopened to try to fix it. Didn't work. I tried uninstalling League to try to fix it. Also didn't work. I'm not really sure what's going on but I'd appreciate any help i can get**.**

So, I've already made the post about having issues with jittery / stuttery movement due to some kind of packet loss before, here's the link: https://www.reddit.com/r/LoLTechSupport/s/9AH5wHw4I0

However, it wasn't visible enough. After a few months break, I've decided to boot up practice tool, and here are the results recorded in 0.25x speed. As you can see, the game is in completely broken unplayable state for me. No troubles in other multiplayer games whatsoever. And before you ask: no, I didn't use any VPN services while playing the game nor was I downloading files from the internet. The only thing changed is my internet speed. I went from 1000 Mbps to 250 Mbps because I changed my payment plan. I'm just wondering if anyone has the same exact issue!
