I have started to get strange results when I convert. The new file appears to be readable and transfers to my Kindle Paperwhite OK but I get an error when I try to copy it to another Caliber library. This not only has started to occur with new conversions but also applies to prior conversions that copied OK at the time of the original conversion.

My error message for one book is:

calibre, version 3.39.0
ERROR: Failed to copy books: Could not copy any books, click "Show Details" for more information.

Failed to copy a book, see below for details

Copying: Odessa Sea-24~B1 failed, with error:

I may have screwed up a setting somewhere but I have no idea what happened. Any help would be appreciated.
