Hi,
I found that 21H2 hadn't been installed (I saw that in update settings). That's odd as I regularly update right after I get the sent requests. Problem still there after a restart.
I did the Troubleshooter Update. No problem found. Problem still there after restart.
I did the system file check in Method 1. The report for both scans was that everything was OK.
For Method 2, a corrupted file was found and corrected. I restarted and the problem was still there.
I agree that the next step is to try to repair or reinstall Office. Any tips for that? I guess I'll need to back up all my office Docs?
Thanks for all your help.
