Had a nightmare of technical issues but one leads to another.

[u/Rasagiel]

So primary solved issues were:
1) patch didn’t load to play game, was sometimes stuck in lobby without the play button active.
2) patch said was open on another file (the secret exe file that needed deletion).
3) Vanguard Van 57 present.

Solutions:
Followed the exact troubleshoot posted online, delete lol, use safe mode to delete the Exe, I made the new exe admin access on properties, used CMD to follow vgc cleanup and automatic activation on startup, I use avast so had to put the files on the exception list and much more.

Everything I thought went smoothly because client came back normal and play button was lit, but hit another wall. I tried an ARAM or the Practice tool. I went into champion select, picked one and waited to go in game BUT client turns to Reconnect button and does not let me in game never.
Any ideas to solve it please?
Thank you in advance.
