Valid PDF cannot be edited in Acrobat
We’ve recently encountered a set of PDFs that cause errors in Acrobat Pro DC.
They are provably valid and syntax error free. We’ve checked the PDFs with:
Adobe's (DataLogics) PDF checker command line
No errors reported.Acrobat's pre-flighting
No errors reported.RUPs (IText)
No errors reported.Enfocus PitStop
No errors reported.
Every other software we've tried can open, read and edit the document without issue.
Yet when these same PDFs are opened in Acrobat DC Pro, we find that Acrobat shows generic errors when an attempt is made to edit the PDF.
Steps to reproduce the issue:
1) Open the supplied PDF in Acrobat Pro DC.
2) Attempt to edit.
Expected result:
The PDF can be edited.
Observed result:
An generic error is raised, with no actionable information. (See attachment)
Environment (OS, other related application versions, etc.):
Windows 10 (Latest)
Acrobat 2021.007.20099
What we ask is that you review these errors in your application, with a view to finding and fixing the bug, since these errors are making our workflow unusable.
The out-works.pdf is a sample using structure tagging, quite similar to the rest, where the errors don’t occur, so it’s not specifically a structure tagging issue.
Note that I've also gone through basics such as re-installing from scratch, etc. My colleagues can also recreate the issue with their installs of Acrobat too.

This always happens with the latest version.

Also a simpler file that reproduce the issue. This one has an attribute owner on the structure element.
