I did a clean 21H2 install, updated it, opened Edge, updated it, closed it, and an hour later try re-opening it and it doesn't open. This happened several times and deleting the user config folder and resetting Edge fixes it (until it seemingly randomly happens again). No extensions No MS account sign-in on Edge Disabled page preload, staying open in background, and starting with windows Edit: Still happens W10 "19044.5737" Edge "135.0.3179.73"; wiping the user profile folder allows it to re-open until it breaks again: Code: RMDIR /S /Q "%LocalAppData%\Microsoft\Edge"
