I’m glad for you. They’re not fun. But they’ve happened to me several times, invariably immediately after upgrading to Windows 10 or installing a Windows update. And I have found plenty of reports from other people having the same or similar issues.
I’ve also had the start menu (and notifications area) completely refuse to open…three times now, I think? And the third time the Settings app refused to open as well and the Windows store and related applications vanished. All known issues! The former has a dedicated troubleshooter tool that did restore start menu functionality for me for a bit. The latter required me using a powershell script to regenerate all Windows default apps, many of which I had deleted for being useless. (Nothing that requires special effort to get rid of, mind you - and if uninstalling apps it gives you the explicit option to uninstall breaks the system, that’s their issue, not mine.) I still can’t get a lot of those or the Windows store to open but I gave up because I don’t actually have any desire to use the Windows store or Maps or Camera (you know, on my desktop machine). Start and Settings are kinda important though.
Anyway, a topic for a different thread since this issue seems to have been Malwarebytes’ bug, not Windows.
