Context

Cause

Resolution

If this is only happening with one single PDF, please try converting the PDF to a newly saved file as it may be corrupt.

Open the PDF outside of TCM
Navigate to File > Print > instead of selecting a printer, choose Microsoft Print to PDF or Adobe PDF. This will convert/save the PDF as a new file.
Attach the newly saved file to TCM and test again.
