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 : https://media.discordapp.net/attachments/175071354087931904/456913412081975307/unknown.png
