I noticed this as well, but other software I tried to open it with also failed in different ways: GIMP, Inkscape, Libreoffice Draw, PDF Arranger. Libreoffice also reports it is "partially signed". Therefore I think the signed PDF is constructed in a particularly hard to handle way, and I have contacted Docusign asking for advice on the topic.

(This does not belong in the ticket here, but in case you - or someone else who reads this - are desperate to get a peek inside the document(s), I found that by following the provided link in the conclusion email, if I choose "combined PDF document" (downloading a PDF) instead of "collection of PDF documents" (downloading a ZIP) I get a working PDF. I am not sure whether this option is also available if you only got a single document, in my case the trasaction included a total of three documents.)

Docusign claims that they comply with PDF 1.5, and that the files is standards compliant. More specifically, the answer I ŕeceived from a Docusign person was: "I discussed this issue with one of the DocuSign Signing PMs. [...]He also said the PDFs have a compressed xref table that only support PDF 1.5 and later. If your pdf readers only support 1.4, they won’t open." I used online tool https://www.pdfen.com/pdf-a-validator both on the attached PDF of the original submitter and on one of the files I received, for the attached, the result is: Status Validation Successful Result The format of the document is PDF1.5 Not PDF/A. For the one I received, the result is: Status Validation Successful Result The format of the document is PDF1.7 Not PDF/A. I will follow up why my file is cialmed 1.7 and not 1.5 contrary to the vendor's statement, but I hope this helps in diagnosing the issue.

I couldn't open a Docusign PDF until I tried PDF Studio.

The PDF in the OP works for me with Atril 1.26.0, and probably more importantly poppler 22.08.0-2.1 and poppler-data 0.4.11-1.
