Code:
try
{
PdfDocument pdfQA = PdfReader.Open(pathtoQAForm,PdfDocumentOpenMode.ReadOnly);
Same code works fine on 30+ other almost identical PDFs. In the error case, the file is signed (3 fields) using both Bluebeam & Acrobat, which is unusual for us. (Generally just Bluebeam and all works fine.)
File displays correctly using Bluebeam, Edge, Win10 Reader, Chrome, PDF ExchangeEditor. Form fields (other then signatures) were filled out using PdfSharp library. (had to split to get under 250k)
Not critical as I can update database manually upon the error report.
