Hi, I'm fairly new to Calibre. Thankyou Kovid for your great work in creating this. I've just upgraded to version 6. I use a Mac (OS Monterey 12.3). I'm not very tech savvy. Apologies if this is the wrong forum too.

I just tried to add several books from Adobe Digital Editions folder but cannot. Here is one error message.

calibre, version 6.0.0
ERROR: Cannot add books: Failed to add some books, click "Show details" for more information.

Worker process crashed while executing job
Traceback (most recent call last):
File "calibre/utils/ipc/pool.py", line 108, in recv
File "calibre/utils/ipc/__init__.py", line 24, in eintr_retry_call

File "multiprocessing/connection.py", line 419, in _recv_bytes
File "multiprocessing/connection.py", line 388, in _recv
EOFError

Before updating, I tried to instal deDRM (several times). I don't know if this succeeded as I could not see this App anywhere on Calibre. I then tried to convert an epub book to mobi for a book that would have had DRM and that seemed to work. Could it be that deDRM is preventing me adding books? If so, how would I remove deDRM? Thankyou
