Critical Error - Can't Find A Fix

Getting a critical error every time my game goes to begin. It happened once, so I restarted League only to met with no option to reconnect. Game gets remade. Figuring it is a fluke I go again. Same thing happens only this time I get a reconnect option. Unfortunately I just get spammed critical errors. I've tried a couples fixes, repairing, and reinstalling. Nothing has worked. I would appreciate some help Riot. I'm not sure what's going on as I just played a game this morning on Lucian.
