Object Reference not set error when converting to Docx/Doc on Linux

Hello.
We use Aspose.PDF.Drawing (23.9.0) for our project under linux .net6, and certain files are throwing
a null object reference exception when trying to save a Document with Docx or Doc format.
I have attached a zip with 3 pdf files that reproduce the issue, a code snippet with the code that reproduces it, and the exception text.

We tried using Aspose.PDF 23.10.0 and it also reproduces this issue, and also using Aspose.PDF.Drawing 23.10.0 as well.

This issue is not reproducible under windows.
