@Kuroch87You are describing the exact same problem I had; believe me, formatting windows 11 again doesn't worked. I tried two times, one with the embedder reset windows, and one with a pen drive. The only thing restore my pc to normal state was going back to windows 10. In every new instalation of Windows 11 event viewer crash, and Epic Games launcher doesn't work normally. Maybe it is a recent windows update, but I don't know, but seems to be a big problem if affects a lot of systems.
