One of mine has been trying to do an update since May I suspect it is stuck due to an obscure audio driver to do with creating sound effects rather than the basic speakers. Periodically it will go through the motions then revert to how it was.
Have tried a lot of things including messing with registry and using the reset options it always gets stuck and reverts.
I think eventually it will need full wipe and start over but if Windows 11 eventually is allowed on it (wrong processor) that might sort it out
