Can anyone help with this error?

Probably not without more information.

I think Kovid said there was 1M lines of code.
Knowing EXACTLY what (and on what OS) you were doing at the time that message popped up.
BTW we also need the Calibre Version #

I've seen that error running Python 2 code on Python 3. This came from a Linux distro supplying calibre 4.23 with Python 3 as the installed flavour of Python. Once the distro calibre was removed and calibre installed from Kovid's site the error went away.

Thanks for the replies. I have two libraries-ebook and hard cover. I get the error when I try to switch to the hard cover library. Details:

The find duplicates plugin you have installed is very old (from 2017) and not compatible with calibre 5. Update it

THANK YOU! That fixed it!
