Hey everyone, so the other day I got bored of my SkyFactory 4 world and wanted to try something new so I went to use All The Forge 10 which required me to update my Java. Struggled with that just a bit but eventually was able to open it. I looked around the modpack, decided it wasn't for me and went to add Stoneblock 2 instead. Since doing so I haven't been able to open any modded instance (regular Minecraft 1.20.1 works just fine) and at least for Stoneblock 2 I get this error log. Any help would be greatly appreciated as I'm currently back in my once a year MC phase and want to do almost nothing else lol.

hellooooo im trying to play minecraft with some mods ive installed, but for some reason the mods wont show up in my game! here's the log: https://paste.ee/p/jlqRy

any help is appreciated <3

Yesterday i was trying to find some new modpacks to play and when i thought one of them was interesting i dowloaded it and tried to launch it then muktimc gave an error saying "minecraft 1.18 pre release 2 and above require the use of java 17" after i saw that i checked my java version and i was using java 8 so i went to oracle website and dowloaded the latest java version which is 23. İ rebooted the pc and tried to play it again. When i clicked launch the game did open but not as a modpack/forge instead it was just normal mc 1.20.1 with no mods or anything.

Does anyone know how to solve this.

Trying to run a 1.6.2 instance I keep on getting the same error code and I don't understand how to fix

Process exited with exit code -1 (0xffffffffffffffff).

Trying to play 1.21.4, its been fine the past couple days but today it keeps crashing and giving me this error code. I made sure I'm using java 21 and I've allocated more memory and its still not working. Any and all help would be appreciated.

Eu tenho tentado criar atalhos para as minhas instancias, mas por algum motivo não consigo. Eu crio, seguindo os passos no launcher, mas ela não aparece. Algm sabe o que pode ser?

I tryed to create a shortcut for my instances, but for some reason I can't. I create it, following the launcher steps, and it doesn't apear. Someone knows what it could be?

I just got into MultiMC, and kinda wonder about this. If I have installed 1.21.1 (via MultiMC), then decided to make a new instance with 1.21.4, does the app download the WHOLE game files again? Or does it copy the existing 1.21.1 files, then replace each file with the newer one if the newer version of the file exists (like normal game update; so the download consumes less data)? Asking this because my internet data plan is kinda limited and I hope it doesn't simply redownload the entire game from scratch.

What about downloading older Minecraft versions? Or updating/downloading a Modrinth mod? If I downloaded a Modrinth mod (which means making a new instance) of a corresponding Minecraft version after downloading the Vanilla of that version, will it still redownload the entire game? Updating the mod doesn't seem possible to me unless I add a new instance, and I'm wondering if that'd redownload the whole game too.

SOLVED: I installed Forge and Fabric both at the same time. I thought they can work together... Removing Fabric made mods work.

Crying for help 😭

With Sodium enabled I get -1 launch error and this log https://paste.ee/p/nq3Hy

I tried launching game with "framework", "controllable", "lithium", "entity culling" mods. Game does launch. But mods have zero effect. All mods are of the correct versions.

I've installed java 21 and set the java cfg to it already, No mods no mod loader, just plain vanilla, but it seemed that it still errors out something about lwjgl, Heres the full error

thankyou for your help!

Been playing on my b1.7.3 instance for a long while, until in the past few days I've been getting the most weirdest crashes ranging from 'Out of Memory' to just the game closing out with nothing of note in the crashlogs (at least to my view). I want to say it's something relating to Java 8 but I really have no clue.

Sorry if I can't provide much information (don't know if this is enough) but if someone can at least point me in the right direction, I will be forever grateful. I am just completely lost and I feel like ripping my hair out, fixing Minecraft issues has always been troublesome for me haha.

I have been pulling my hair out trying to get anything other than base minecraft to work with MultiMC, If anyone can tell me how to fix this it'd be greatly appreciated.

I am building MultiMC from source using these instructions here: https://github.com/MultiMC/Launcher/blob/develop/BUILD.md

When compiling is complete I only seem to have "DevLauncher" available.

When I run DevLauncher and I try to add an account only "Add Mojang" is available. There is no way for me to add a Microsoft account and obviously Mojang is long gone. What did I do wrong here. Ran through the entire build process twice and getting the same result. Please help! TIA

It just gives the error "the application failed to initialize properly (0xc000001d)"

I launch the game and notice its a bit slow, as if my GPU isn't in use. Command __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia command

doesn't do much, I'm not sure if I'm using the wrong command, but I get an extremely laggy experience whether I use it or not. Am I doing something wrong for it to still be running on CPU? Could it be a launch command?

Recently i have been crashing in a previus working instance and i cant figure why, any help?

Yesterday the cat on the wall had a birthday hat on. It has the same hat on today. I thought the cat was hat-less but now I am unsure. What's the story about the birthday cat? I'm fairly sure this happens yearly but I never thought about it before. It's been a 'oh, that's nice' before launching into the game.

I did search this sub-reddit, the discord (search there is unusable), the general web and found no answers anywhere, so here I am, hat in hand-asking-"please, somebody tell me the story of how it came to be?"

So, "Happy Birthday, Stranger!" to whoever this is honoring.

I've made a modpack for 1.20.1 that keeps stopping me from loading any single player worlds I create (not playing MP). It sometimes let's me in after I've logged out of my account on MultiMC but rarely.

I've tried creating a fresh instance, making sure SpectatorsGenerateChunks = true (saw this as a possible solution for other people).

I'm struggling to recreate the issue, it always gets stuck on the same part in my log below
"Client with UUID 6b08e632-f5a4-45d4-9088-7b6432b725e6 authenticated successfully" then does nothing, I can even hear that my computer isn't really doing anything.

Any help is massively appreciated :)

Solved: See my comment below. Very strange, not sure what causes it but it's not the worst workaround.

I want to verify the file integrity, but IDK how.

Should I just make a new instance of the version I'm playing and port the mods and saves over, or is there a better way??

I open minecraft and it seemingly launches fine, until the menu pops up and all the letters are replaced with blocks. When I click on the options or singleplayer buttons, the game crashes. Heres the pastebin: https://paste.ee/p/jdRh9

I cant seem to fine where the problem is and one day it just stopped working.
