I am using GroupDocs.Conversion 20.10.0 with .NET Core 3.1, running on Windows 10.
PDF documents created from certain Word documents (docx) cause an error when the PDF is viewed in Acrobat Reader:
“There was an error processing a page. There was a problem reading this document (111).”
Most of the content is cut off after the first heading or block of text.
The PDFs can be viewed OK and look fine in Chrome.
I built a quick console app to try the conversion with all the different PDF formats, and all of them cause the same error.
Here is a Dropbox link to the repro project along with the sample document and the outputs: https://www.dropbox.com/s/kg4nxz4e0gkde9b/AcrobatError.zip?dl=0
