Got the same problem, both with Kobo Touch Extended Driver and Kobo Conversion Plugin... latest version of Calibre and plugins, it fails on every book I tried...

Any hint?

calibre, version 5.33.2

I don't know if I should post it here or in the thread of the conversion plugin, as it's throwing the same error. Could you help me?
