[Crash] League Client critical error

Yes, hello, I have linked a crash dump from Dropbox, I am experiencing this issue that occurs directly after champion select as the game is transferred to the client the whole screen goes black and I am never to experience the "boarders" part of the game loading... instead I am introduced to a black screen and 2 screens indicating the game has crashed, I have attempted updating windows, restarting PC, repairing my SSD, and running as administrator to which none have solved the issue... I don't understand how computers/applications can go from preforming perfectly to not functioning in any capacity within a period of 24 hours so maybe someone out there can assist me.
