[X ] I am using the latest version of calibre to report this bug, which is:
[ X] I am using an official calibre release, not one from a third party (e.g. your Linux distro, Flatpak, Chocolatey package, Homebrew, etc.)
[X ] I am using the latest version of this plugin, which is: 3.4.3
[X ] My operating system is (e.g. Windows 10, Windows 8.1, Windows 8, macOS 10.15.5, Fedora 32, Arch Linux, etc.): Windows 11 Home, Version 21H2
[X ] I have included the full, complete, unmodified debug log from calibre
- Directions for getting the debug log are under the "Logs" header below.
[X ] I have translated the text in any screenshots and logs to English, or all screenshots and logs included are in English.

These items are optional. Fill in as much of them as possible. If something is not applicable to your bug report, note that.

[n/a ] I have installed the Scramble Epub plugin (see https://www.mobileread.com/forums/showthread.php?t=267998) and will attach a scrambled copy of the book I'm having problems with (attach a file by dragging and dropping onto the Github editor).
- [n/a ] If this is a conversion bug, I will also attach a scrambled copy of the converted book.
[n/a ] The path to my calibre library or to a book in my calibre library has non-ASCII characters: yes/no
[ ] If I am using Windows 10, I (have/have not) enabled Windows' beta support for Unicode (see https://www.mobileread.com/forums/showpost.php?p=3988195&postcount=2052) I'm using Windows 11, so I'm not sure if this is still necessary
[ ] If I am using Windows 10, does this bug happens with beta Unicode support both enabled and disabled, only when enabled, or only when disabled? I'm using Windows 11, so I'm not sure if this is still necessary
