Book_fmt Error: WordDumb won't create X-Ray nor WordWise

[koleso40-ui]

Please could someone help me figure out what is going wrong?

I get the following error when I try to run Worddumb on EPUB/KFX files: AttributeError: 'MetaDataResult' object has no attribute 'book_fmt'

Here is the whole error message:

• MacOS is updated to 15.7.3,
• python version 3.11.5
• Calibre 7.26 *downgraded it because I figured that might solve the issue, but it didn't.
• Kindle Previewer 3 ver 3.101.0

In Worddumb preferences I set the python path to: /Library/Frameworks/Python.framework/Versions/3.11/bin/python3.11

This is another error I get if I try to execute on a file that has only KFX:

Welcome to dependency hell: Please delete the '/Users/ekaterina/Library/Preferences/calibre/plugins/worddumb-libs-py*' folder then try again.
