Hi,

After installing macOS 12.0.1 Monterey I cannot import epub files anymore. I get the following error:

calibre, version 5.30.0
WARNING: Errors while adding: There were problems adding some files, click "Show details" for more information

----------------------------------------------------------------------
Failed to add the file /Users/davidwb/Desktop/kallen.epub to the book: /Users/davidwb/Desktop/kallen
With error:
Traceback (most recent call last):
File "calibre/gui2/add.py", line 488, in add_formats
File "calibre/db/cache.py", line 1573, in add_format
IsADirectoryError: [Errno 21] Is a directory: '/Users/davidwb/Desktop/kallen.epub'

When I add PDF, JPG or mobi it works just fine. I have tried

- different users on the Mac,
- a new empty library
- moved the library
- upgraded Calibre
- tried several different epub files
- tried import from different directories

...and it is still the same.

I will try to attach a movie of how it looks. See attachment.

Does Calibre not support Mac OS 12?
