Game crashes every time I alt tab to desktop after update

each time I alt tab to desktop while the game is running it crashes. has happened while looking at the main menu, while loading into a game, and while actually playing a game. This has only begun after the new patch and season 5. Prior to that there was no issues with alt tabbing back and forth during matches, etc.

Hey @weedonastick! Next time you crash, will you immediately contact support with your DxDiag and warnings.log file? It will help us investigate. Thanks!!
