Same error.

Downgraded pymupdf as workaround:
pip3 install pymupdf==1.23.8

[manateelazycat]

@luhuaei Can you help to fix this?

[manateelazycat]

I have install pymupdf 1.23.9, can't reproduce this issue.

[longminwang]

Another workaround is to replace import fitz by import fitz_old as fitz.

Please see
New 'rebased' implementation of PyMuPDF
PyMuPDF-1.23.9 released
for details.

[luhuaei]

I can reproduce the problem, I use pacman -S python-pymupdf

>>> import fitz 
>>> fitz.version
('1.23.22', '1.23.10', '20240212000001')

pymupdf/PyMuPDF#3177
pymupdf/PyMuPDF#3182

[luhuaei]

Fixed in pymupdf 1.23.25
