An Overwatch 2 bug is causing some PCs shut down or restart
Overwatch 2 players can't even play the game in peace
There is a new bug affecting PC players and that's the Overwatch 2 shutdown bug that happens in a queue for a match. There were many reports of the new issue on the Blizzard forums and the good thing is Blizzard has been notified about the issue and actively investigating.
Blizzard is asking players who have encountered the issue to aid its investigation by providing it with their DXDIAG.
Finally, it's probably best to refrain from playing Overwatch 2 on PC for the time being until the developers figure out what's causing the issue and can deliver a fix.
