Running into this issue when opening a specific PDF file:

Code to reproduce the problem

file = "sample_file.pdf"
with pdfplumber.open(file) as pdf:
    print(pdf.pages)

PDF file

sample_file.pdf

If you need to redact text in a sensitive PDF, you can run it through JoshData/pdf-redactor.

Expected behavior

I should be able to access the page objects from the PDF. I tried opening it with PyMuPDF and it works.

Actual behavior

Got the error message.

Environment

pdfplumber version: 0.7.6
Python version: 3.9.16
OS: MacOS Big Sur, conda environment
