New Update crashes without launching (not a directx12 option issue)

This is unbelievable. Since the update yesterday I can't play a single hour of the game without crashing to desktop. Happened two times yesterday night (in ranked matches) without a single error message. Crashing today after playing 2 matches with error message saying there's something wrong with the files and I should repair the game which I did but it keeps crashing. Anyone else's game constantly crashing?
