League of Legends won’t launch / “Play” button doesn’t work and keeps asking to restart the PC

Hey guys, I’m new here and I need some help because my LoL just doesn’t work anymore.

I’ve pretty much tried everything:

  • updating the game

  • repairing the files

  • uninstalling and reinstalling

  • updating again

  • restarting the PC several times

Even so, the client keeps asking me to restart the computer all the time, and I can’t even click the «Play» button. Sometimes the LoL menu doesn’t even open.

I have no idea what else to do.
Has anyone gone through this or knows a solution? Could it be an issue with Vanguard, Windows, the Riot client or something like that?

Thanks in advance :folded_hands:
