I was able to finally resolve this on my end. Results may vary of course. This was on Server 2016 Datacenter. I initially could not add the xps document writer due to element not found. Copied the documents writer folder from a known good server of the same OS over to the problem server, ran windows updates, this allowed me to re-add the document writer, ran the quickbooks tool hub, selected program problems, and ran the quickbooks print & pdf repair tool. Once all of that was done the user was able to send the reports as a pdf again. Hope this is helpful.
