League of Legends caused ACCESS_VIOLATION in module League of Legends help!

it all started yesterday when i tried to log back onto league and i got a black screen after hitting launch. now i fixed that, but now i have a problem where i go into champ select and pick my champ/role/summoner spells. but as soon as it gets ready to go ingame it crashes, even before i get to the black screen. the client closes like normal but instantly comes back up saying the game has crashed try to reconnect. please help.

things i have tried 1)deleteing logitech files 2)adding it to firewall 3)updating all my drivers 4)deleting item sets and persisted settings 5)repaired the client still nothing
