I am running latest w11, and without notice my laptop failed to boot properly. It does boot but the file manager keeps crashing so the desktop just flashes the icons and a black screen with no task bar.

I have run SFC and dism restorehealth but no problems there. Chkdsk does have some problem with orphaned entries. It does get fixed with chkdsk c: /f and reboot either.

I have a second Nvme SSD installed and that still boots fine. But it won't load the C drive from the other SSD. 

I am stuck on where to go next without a complete reinstall.

Any thoughts
