A couple of nights ago at work I started my laptop in Safe Mode. When the desktop appeared it was only for a second, then white screen for a second, then desktop for a second. Over and over. I messed around for awhile with it and finally using another computer I made a Windows 11 install USB. With that I was able to boot it and get into recovery mode and restore to an earlier date. When it restarted the laptop it was still in Safe Mode but was OK and I was able to change it back to normal. Over 2 hours later is was.
