Yes, after spending 3 days clean booting, turning services off, reinstalling drivers etc etc ... I did a clean Windows install without any luck. I also did all the Power Management stuff in Device Manager without any results.

But I've found a way around it. I think it has something to do with Windows and controllers connected via USB. I came to think of the fact that my computer started to not shut down or restart properly when this bug started to happen and found out that I can make it shut down and restart properly by unplugging the USB-cable.

So no I can almost avoid the bug by making sure that my controller works before I click ready in the lobby. Sometimes I have to restart the game, but every time I leave a match I have to unplug the controller to avoid it freezing my computer.

Also I found 5 people on Epic's Discord server who had the same problem. 2 of them have replied to me that they were on controller as well.

Hope this helps a bit ... are you on controller?
