i use PdfLoadedDocument with openAndRepair = True and it does not detect digital signatures
in this file pdf version 1.7
PdfLoadedForm = nothing
Dim pdfdoc As New PdfLoadedDocument(OpenFileDialog1.FileName, True)
Dim form As PdfLoadedForm = pdfdoc.Form
however it worked fine with other files of same pdf version 1.7 or less
i tested using latest nuget for windows forms 20.3.0.60
