This error happens both on macOS (as one user reported in the Addon's comments), and Windows 10. The user experiencing this error was using anki 2.1.23 on macOS, while I experienced this error while using anki 2.1.22 on Windows 10. I checked that I was using the newest addon version. This issue happens even if you don't change any of the settings and just hit save.

Hopes this issue can be resolved.
Cheers,
Hades.

Thanks for the report.
I am working on it, however I cannot tell when it will be done.
