Failed updating book from ...

_Originally posted by @stacsk in [#239](https://github.com/tfonteyn/NeverTooManyBooks/issues/239#issuecomment-4198428486)_ I'm getting an error when I'm trying to save this particular book (no problem with scanning), and I'm not sure if it's related to this bug. The logs are attached. The first pop-up info button shows "insert Book-Author" (author box is already filled), when I press OK and try to save it again, it shows that long message that starts with "Failed updating book from DataManager..."
