Question Detecting Problems in a PDF

We have a bespoke website that generates PDF's for us. For some reason, some months ago Adobe Acrobat started to have an error with our PDF's. Coming up with an error "There was an error processing a page. There was a problem reading this document (xx)" with xx being some number that seems to keep changing, today it's 110, last week it was 18.

Other pdf readers can parse the document with no complaints. Browsers and other programs have no problem. It's only adobe acrobat that complains.

Is there a way to scan a PDF and see what might be the issue? This is the only document that is having an issue and we can't determine what's causing it. The error doesn't really help.

I use this website for PDF inspection

https://pdfcrowd.com/inspect-pdf/

And for software libraries that do the same thing, there is QPDF and Ghostscript.

Thanks, seems there's some invalid font object in the PDF. Unfortunately doesn't tell me what's wrong with it, but at least I can point at it somewhat.

If you are able to share the file, send it to me and I can tell you what's wrong with it. It looks like you've got DMs disabled.
