Symptoms

Whilst playing Overwatch 2 if I tab out and try and watch a video or any stream, then the audio for both programs will start to stutter, and my PC will start to stutter as well. Slowing down until nothing moves, I can't open or close anything or make any movements, then it finally crashes. After it crashes I recognize that all my network devices are disconnected and get reconnected quickly after. This also occurs if you never tab out but play around 5 games.

Reproduction

1. Set Overwatch 2 to use proton experimental
2. Start game
3. Try to queue for a match
4. Whilst queuing tab out the game and start watching video content (either Youtube or a Discord stream should work)
5. (Can also happen on home screen or in game, I found it mostly happened during queue)
