Thank you for contacting support.

We have not been able to reproduce the issue in our environment. Would you please share sample application containing SSCCE code so that we may again try to reproduce it, and investigate further.

my code is (the error line is marked):

Imports Aspose.pdf
Imports Aspose.Pdf.Text
Imports Aspose.Words
Imports Aspose.Words.Saving

Please always share narrowed down code snippet. We have converted it to SSCCE but the issue is not reproduced.

Dim fileName As String = dataDir & "AllJobs_3195556_u6yw4dl.pdf"
Dim fileArr = Split(fileName, ".")
Dim fileType = fileArr(UBound(fileArr))
If LCase(fileType) = "pdf" Then
    Dim docHtml As New Aspose.Pdf.Document(fileName)
    Dim textAbsorber As New TextAbsorber()   ' =====>  !!!!!! the error is thrown here !!!!!!
    docHtml.Pages.Accept(textAbsorber)
    Dim extractedText As String = textAbsorber.Text
    Console.WriteLine(extractedText)
End If

Kindly share narrowed down sample application so that we may investigate further.
