Hi, sorry if this is the wrong place to post, I've searched in the forum for a bit and couldn't find something regarding this specific problem I have.

Whenever I open the get books section and search for books using a keyword, I get a lot of pop-ups displaying the following error message:

calibre, version 6.13.0

This does not occur when I only select archive.org and feedbooks as a source, so maybe it has a problem with certain stores only? I could do a binary search to find the broken stores, but maybe I'm just missing dependencies? Obviously, there is a problem with python, but it also refers to patterns and what I assume to be search syntax.

Thanks a lot in advance and please remove this post in case it is a duplicate or in the wrong place.
