Does anybody here encountered using java aspose slides library that it cannot load a PPTX file with an embedded chart on it?

I use Aspose-Slide 23.10, 23.11, and 23.12 but exception happens.

Here is the snippet:

Presentation presentation = new Presentation(pptfile.getPath());

I got this exception:

Exception in thread “main” class com.aspose.slides.PptxReadException: Cannot invoke “com.aspose.slides.internal.ld.cf.dq()” because the return value of “com.aspose.slides.internal.ld.td.dq()” is null —> java.lang.NullPointerException: Cannot invoke “com.aspose.slides.internal.ld.cf.dq()” because the return value of “com.aspose.slides.internal.ld.td.dq()” is null
