I’ve had the same issue since launch too. Overwatch 1 worked fine for years. I have to pray every time I open Overwatch 2 and hope I get to play. I did everything on all the tutorials. Updated Windows10. Updated GTX 1080 driver. Reinstalled Battle.NET. Reinstalled Overwatch 2. Delete Razor Chroma DLLs. Scan and Repair files. None of these seem to be the issue. It has to be Overwatch 2 being super picky about services or they have a deadlock algorithms in their application. Otherwise why would I be able to open it, close it, then be unable to open it again. Then after like 10 tries, it opens again. This is soo frustrating as I really want to play but have only been able to play once or twice a week.
Hdr perhaps? Turn hdr off in nvidea panel. 2 screens going black could be a gpu issue.
