Game Crash

I have been playing division rivals and idk what glitch there is; every time it reaches halftime, the screen blacks out and I can't do anything. I tried so many fixes; it didn't work. I lost the match because of forfeit. even though i was winning every single one of them. I need my ranks back because it's not my issue and i was winning them. I played a lot and tried everything. I need to be compensated. please help me outttt.
