Crash whenever in-game client launches

After the patch today, which from what i understand is the new anti-cheat, every time that the in-game client launches after champ select, the game crashes and every attempt of reconnect gives me the same issue. This is the system error that's popping up after the crash : same crash message as this post https://boards.na.leagueoflegends.com/de/c/bug-report/NEL66str-crash-whenever-in-game-client-launches?comment=0000
