If you want to play with different versions of calibre I would suggest copying your library and then use a version of calibre portable on your copy of the library.
As the database control changes between versions, you are advised to use copies of your library whilst giving it a go.
I think though that your problem may with the update to windows 11 as you suggest.
Sorry I can’t help you more.

It is uplifting that people care and try to help others. I'm grateful that you have taken the time to help. Someone with more knowledge than I have could probably use the info that you and others have provided, and truly fix the problem. The portable version works, however so thank goodness for that!
