Aspose.Slides stuck when converting PPTX to PDF

I am using latest version of Aspose.Slides - 21.8. When I try to convert a pptx that contains a specific chart to pdf conversion hangs.
Data is specific - as values are below zero and min value in the chart is set to zero.

Attached you can see two pptx documents

  • stuck.pptx - that is causing the issue:
  • fixed_modifed_axis.pptx - can be successfully converted to PDF - min and max values Y axis values are modified (for both axis).

My code is really simple:

    using (Presentation presentation = new Presentation(@"stuck.pptx"))
    {
            MemoryStream stream = new MemoryStream();
            IPdfOptions saveOptions = new PdfOptions(); 
            presentation.Save(stream, SaveFormat.Pdf, saveOptions);
    }
