The game crashes after 20-30 minutes

I'm having problems with this update. After playing a few matches, the game crashes and then it directly freezes my entire PC, and the only solution is to force a shutdown. The game worked fine before, and the problem started a few days ago. I'm not sure if I'm the only one, but it's not my PC, as I've tried other even more demanding games and they haven't given me any trouble. I was forced to format my PC because I thought I had a virus, and the problem still persists. Please help
