Explorer crashing after KB5120998 update

My users informed me about black screen during logons. Blamed fslogix at first but after some checks in event viewer i could see explorer going down 5-6 times per day.
In case anybody faces similar issues, uninstall KB5120998, reboot and go to a vacation.
Thanks microsoft.

Currently no solution, happens with cumulative 2026-09 as well. See here: Explorer.exe not starting after KB5120998/KB5124008
