Game freezing for no reason

I have a decent pc and i usually run the game at 300 fps so its not a hardware limitation most likely. The game fully freezes when im booting it or when i find a match and i cannot even alt-f4 it the only option i have is to unplug the pc fully. I checked all my drivers, updated windows, vanguard is fine, temps are ok and no resources are being hogged by side processes. im at wits end someone help
