HTML to DOCX conversion throws InvalidOperationException using C#

Hi, I am facing an issue when converting Html to Word (docx) documents using Aspose.Words nuget package version (19.11.0) in .Net application and seeing this error message:

More than 63 cells per row is not supported for this file format

I understand that more than 63 cells are a limitation but I could not identify 63+ cells in a table in the sample document I have attached for your reference.

I am using the following code to convert document(s):

        var htmlLoadOptions = new HtmlLoadOptions();
        htmlLoadOptions.PreferredControlType = HtmlControlType.StructuredDocumentTag;

        // Setting the Enconding
        htmlLoadOptions.Encoding = Encoding.UTF8;

        // Create a new class implementing IWarningCallback which collect any warnings produced during document save.
        var callback = new HandleDocumentWarnings();

        // We assign the callback to the appropriate save options class. In this case, we are going to save to Word
        // so we create a HtmlLoadOptions class and assign the callback there.
        htmlLoadOptions.WarningCallback = callback;

        // Load the Html document into memory
        var document = new Document(info.File, htmlLoadOptions);
        
        foreach (Table table in document.GetChildNodes(NodeType.Table, true))
        {
            foreach (Row row in table.Rows)
            {
                row.RowFormat.AllowBreakAcrossPages = false;
            }
        }

        info.File.Close();

        // Convert the document to a different format and save to stream
        var streamResult = new MemoryStream();

        var options = SaveOptions.CreateSaveOptions(SaveFormat.Docx);
        options.TempFolder = WorkingDirectory;
        document.Save(streamResult, options);

Can you please examine the data to check why this is the case as hundreds of documents are throwing the same error at conversion time?

Thanks in advance.
