Forced Out Of Game Screen Randomly Bug

Has anyone else have this problem where you get into a game and then at random whether it's buys things for your build or fighting other players; your screen will take you out of the gaming screen and gives you a black screen for a bit when trying to go back into the game?

I don't know what's causing this to happen and I've tried to repair it over and over and over again but nothings working I've uninstalled and reinstalled it onto my computer. If anyone know what this is and how to fix it I'd be super grateful to you.
