Slide.GetThumbnail Method Saves Bitmap without 3D Chart in C#

I am trying to save a 3D chart slide to an image, but I get an image without a chart.
It is screen from pptx:
image.png (16.1 KB)
It is result jpg file:
image.png (6.4 KB)
It is my code for saving:

Bitmap bmp = sld.GetThumbnail(5f, 5f);
bmp.Save(filePath, System.Drawing.Imaging.ImageFormat.Jpeg);

I am currently using Aspose.Slides for .NET v 20.7.0.
