Exception"out of memory" while loading PDF using Aspose.PDF for .NET

Aspose.PDF Product Family
1

This code used to work previously. Recently, we upgraded to version 20.1.00.

Here is the code:
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(Path.Combine(Server.MapPath(@"~/Templates/" + pdfFileName)));

                        Page page = pdfDocument.Pages.Add();

                        TextFragment tableDescription = new TextFragment(ConfigurationManager.AppSettings["paaPDFTableText"])
                        {
                            Position = new Position(0, 0),
                            HorizontalAlignment = HorizontalAlignment.Center
                        };

                        page.Paragraphs.Add(tableDescription);

                            pdfStream = new MemoryStream();

                        pdfDocument.Save(pdfStream, SaveFormat.Pdf);

The last line gives the OutOfMemoryException. If I remove page.Paragraphs.Add(tableDescription);, this does not happen. Please advise.

Upgrading does not help. Here is the source:

       static void Main(string[] args)
    {
        Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(@"F:\Projects\AsposeTestCs\SomeDocument.pdf");

        Page page = pdfDocument.Pages.Add();

        TextFragment tableDescription = new TextFragment("Some text that should be displayed")
        {
            Position = new Position(0, 0),
            HorizontalAlignment = HorizontalAlignment.Center
        };

        page.Paragraphs.Add(tableDescription); // This causes the trouble

        MemoryStream pdfStream = new MemoryStream();

        pdfDocument.Save(pdfStream, SaveFormat.Pdf); // Exception happens here

    }
