I got a black screen when I was finish 2 matches during the game.

It happened last night when I was trying to get to the next match before it was late last night. BC it was my last one for the day so BC I was trying get out of the match it got to this black screen I couldn’t see nothing on the screen it’s not my GPU it’s 100% the game. My GPU 5070 Ti  I’ve had it for a year now. It’s been working great since have bought it. My CPU it’s AMD Ryzen 7 9800X3D had it for a year now my has been working great since have bought it. Don’t seem to be what’s the problem here.
