Windows 10: Restoring previous version of windows and blue screen

I recently updated to windows 11 but some apps did change not open for me so I tried to go back to windows 10 through the settings. Now my pc is stuck on the “restoring your previous version of windows” and I get a BSOD after 2 min of the loop. The stop code is system service exception.

:)

 

Can someone help with blue screen while restoring previous windows version?

I wanted to revert back to windows 10 from windows 11. The screen shows "restoring your previous version of windows..." for a bit then it would blue screen. The blue screen shows "NTFS.SYS" on the bottom. It would then restart and go back to "restoring your previous version of windows" only for it to blue screen again. It's on this loop and I don't know what to do to fix it. Can someone help?

 

Restoring to previous version of your windows

Windows 10 Fall Update (build 1511) showed up on my Windows 10 Pro laptap. It went through all the steps including the final "speed-o-meter". When it reached 100%, the "speed-o-meter" disappeared and up popped the start screen displaying the message "restoring
to previous version of your window". I did a command line "winver" and indeed, it reverted back to my previous version. Any suggestion? No error messages displayed.
