Further information

Tested with rpm and flatpak version. Both fail with the same error.

[Leseratte10]

Flatpaks or other calibre versions coming from the Linux distribution are quite often causing issues with plugins. Would you mind trying the Calibre version straight from their website, using the installer, and see if that works?

[naxi0815]

With the Calibre version straight from their website it works. Although I am not happy with manually install and maintain software it seems the way to go.

If you found this on google, this issue can be fixed by installing the python module crypto globally. E.g. on Fedora: sudo dnf install python3-crypto python3-oscrypto. You can probably also try installing the module using sudo pip install crypto, but I didn't test it and don't recommend it if a package from your distribution is available.
