Every single book in my library has "Error" listed as the page count, based on the new built-in pages column. I have tried regenerating them for single books and it still fails. If I go to the bookshelf view and look at the page count log, I get the following log:

[2026-02-22 18:31:21.940476+00:00] Failed to count pages for book 22460 EPUB 'The Hobbit: Or There and Back Again', with error:
Traceback (most recent call last):
File "multiprocessing\connection.py", line 338, in _recv_bytes
BrokenPipeError: [WinError 109] The pipe has been ended

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "calibre\db\page_count.py", line 163, in count_book
File "calibre\library\page_count.py", line 244, in count_pages
File "calibre\utils\ipc\__init__.py", line 20, in eintr_retry_call
File "multiprocessing\connection.py", line 256, in recv
File "multiprocessing\connection.py", line 353, in _recv_bytes
EOFError


It is the identical error for every book.

I have the latest version, 9.3.1, Windows portable install.
