ArgumentException Error when Saving PowerPoint Document in C#

Aspose.Slides Product Family
1

Running this code:

        byte[] binaryFile = new byte[file.ContentLength];
        file.InputStream.Read(binaryFile, 0, binaryFile.Length);

        var doc = new Presentation(new MemoryStream(binaryFile));

        var ms = new MemoryStream();
        doc.Save(ms, Aspose.Slides.Export.SaveFormat.Pptx);

Gives the error message: An entry with the same key already exists.

I have the same PowerPoint translated into different languages, but it’s only Arabic which doesn’t work, I have been working with many Powerpoints and Aspose before and this error message is unique for me.
Is it something wrong my my code or a bug within Aspose.Slides?

I am using Windows 10, Aspose Slides 21.1, Dot.net 4.8

Arabic.7z (2.8 MB)
