I haven't tested the program with Windows 11 since I still run Windows 10. On Linux it still works for me with pypdf2 1.27.7 (the latest version). They have started development back again, though, so it could be a bug in the 1.27.6 distribution. Try upgrading pypdf2, or maybe regressing it to something like 1.26.0 if that doesn't work.

If that still doesn't work, open a Python shell instance and type import PyPDF2 and see if your system is correctly set up to do the imports.

I tried the exact same steps today and it works 😄 I think it was because of this bug in pypdf2 and it's fixed in a recent release yesterday (version 1.27.7)

I believe this needs to be reopened as the same breaking change was implemented in pydf2's 2.0 release. Either https://github.com/abarker/pdfCropMargins/blob/master/src/pdfCropMargins/main_pdfCropMargins.py#L71 should be importing from PyPDF2.errors and require a 2.x release of PyPDF2, or this package should require a 1.x release.

I pushed a bug fix out (1.0.6) which tries the errors module and then the utils module if that fails.

This fixed things for us downstream, thanks.
