I have converted a *.pptx presentation to *.pdf format with Aspose.Slides and the result document missing shapes on several pages.
The presentation and an example of a missing shape (image) are in the attached archive.

Code sample:

var pr = new Presentation(inPath);
pr.Save(outPath, SaveFormat.Pdf);

I use Aspose.Slides.dll 25.2.0.0.

I have tried again and this time there is an empty square with an error icon. The shape on the next slide is missing.
I tried a few more times and the shapes usually disappear.
I attached the result *.pdf.

I have been unable to reproduce the issue on my end, and I am having difficulty identifying the root cause on your side. Perhaps the cause is related to your environment.

I found the reason.
I build my project as AnyCPU and Windows launches it as a 32-bit application by default.
When the project is built as an x64 application there is no issue, but the memory usage goes over 5GB from time to time.
