I've never changed anything

There is your clue.
Because Microsoft 365 is a cloud-based technology, it requires interactive browser functionality.
This functionality is provided, in part, by JavaScript.

The error I got in Office was related to Javascript not being enabled, but I've never disabled it anywhere.
I'm not going to logout of Office to recreate the error message, I had to use a recovery image to get my signed-in Office back

Glad you got your Office functionality back with no error exiting the various applications.
This could help someone, so pretty please mark it as solved.

The issue isn't solved!
The apps were crashing on closing, I re-installed Office using the offline installer and got back into Beta channel, they were still crashing on exit so I signed out of Office to see if that helped. Apps didn't crash with the non-beta version
It was THEN I couldn't sign back in as I got the Java error in Office. I had to use an image backup where I was still signed in
The apps still crash on closing unless I End task using Task manager
Java is enabled in Edge as it always has been

All the Office apps run as they should, the error occurs when I click the Close window 'X'

Another PC here is having the same problem
