Game Keeps Crashing

I opened Steam and started up the game, and there was a pop-up for me to click yes or no for the game, and I unfortunately just clicked yes. I think it may have been the anti-cheat. It was literally today. Well, now my game continuously crashes while playing. Maybe a minute or two of normal play, then it just crashes. I have to hit play again in Steam, and it brings me back. But the last two times it crashed, it forfeited my play, which is extremely annoying. 

I've updated my Graphics card, computer, and BIOS so far. I'm almost wanting to try to delete and redownload apex. 

Help!
