Unexpected EOF with PdfReader.Open(PdfDocumentOpenMode.Import) when opening a PDF with a textbox and slash

[nh104622]

Basically title. When I try to take in an existing PDF byte array then open up a memory stream to read the PDF then Call PDFReader.Open(...), I get an error message with the below external stack trace. The issue goes away when I take out the slashes in a date text field of the editable PDF. The example PDF has a date in the format of: 01/01/1970 in a textbox. Is there any way around this issue?

using var stream = new MemoryStream(pdfData);
using var doc = PdfReader.Open(stream, PdfDocumentOpenMode.Import);

An update on this issue, I still have this problem with an inconvenient workaround. Basically this PDF I am trying to import has editable fields and generates the above exception when calling PdfReader.Open(...). The workaround is to manually edit one of the fields using Adobe then undo my change and save it. For some reason this seems to work when re-running my application with the above code.

Does anyone have any insights on what could be happening here? This happens with multiple documents.
