Fail to remove drm wtih Obok with Calibre and Kobo desktop app

Question / bug report

If I use obok with Calibre, it can't remove drm.
btw, But I usually use obok.py directly. It can work normally with python-3.10 and PyCryptodome. Although it has some minor issues, such as overwriting files with the same name if some books have same name.
Which version of Calibre are you running?

7.11
Which version of the DeDRM plugin are you running?

10.0.9
If applicable, which version of the Kindle software are you running?
