Saving PowerPoint File to PDF Format Causes Hanging Program

Hi,
I’m testing Aspose Slides 21.2 and there is an issue with a sample file.
When loading the file and saving it to PDF format, program is hang. (Output filesize is about 15KB then hanging).
Sample code:

using(var presentation = new Presentation(“sample.ppt”))
{
presentation.Save(“outFile.pdf”, SaveFormat.Pdf);
}

I’m using Aspose Slides 21.2 .NET. Here is sample file sample.zip (7.1 KB)

Please help to check it.
Thank you.

@dunghnguyen,
Thank you for the issue description. My antivirus program detected malware in your sample.zip file. You should check that problem first.
