The attached pdf is created by PDFSharp:

string source = filepath_mage;
string destinaton = filepath_pdf;
using ( PdfDocument doc = new PdfDocument() )
{
XImage img = XImage.FromFile(source);
PdfPage nxpage = new PdfPage();
doc.Pages.Add(nxpage);
XGraphics xgr = XGraphics.FromPdfPage(nxpage);
XRect srcRect = new XRect(0,0,img.PixelWidth,img.PixelHeight);
XRect dstRect = new XRect(0,0,nxpage.Width.Value,nxpage.Height.Value);
xgr.DrawImage(img,dstRect,srcRect,XGraphicsUnit.Point);
using ( Stream nxream = File.Open ( destinaton, FileMode.Create ) )
{
doc.Save(nxream);
}
}


It cannot be read by PDFSharp:

PdfDocument inputDocument = PdfReader.Open(file,PdfDocumentOpenMode.Import);

Exception: PdfSharp.Pdf.IO.ObjectNotAvailableException: 'Cannot retrieve stream length.
PDFsharp cannot read this PDF file. If you think your file is a valid PDF file please send it to us so that we can fix this bug in the PDF parser.'

Thanks.
I don't know where you sent it.
Consider uploading it to GitHub.
