You're now Windows 11?
Have you disabled Windows 11 Fast Startup?
Have you tried machine Restart (not Shut down)? 
Have you tried to refresh your Norton 360 install?

Did you try running Norton Remove and Reinstall tool -> Remove & Reinstall?
Did you try running Norton Remove and Reinstall tool -> Advanced Option -> Remove Only?

IDK if Norton Remove and Reinstall tool supports Windows 11
