I had a couple of really bad days trying to figure out what happened and why I was getting black screen, until I reset my laptop and then I see this on the elevenforum.com about StartAll Back is the culprit: https://www.elevenforum.com/t/kb5021866-windows-11-insider-beta-build-22621-1028-and-22623-1028-dec-6.10979/post-229976
Are there any safeguards against something like this happening again in the future?
