Blackscreen

Hey,

I have a problem in the game, when the match ends and I want to leave the match and go back to the lobby, a black screen pops up and I can't do anything but turn off the game with alt f4 and turn the game back on. The game runs without any problems, I recently bought a new PC, but I only kept the old SSDs, the game runs stably at around 250 to 300 fps, I don't know what to do anymore.
