… outPres = new Presentation();

 outPres.getSlides().removeAt(0);     // remove first blank slide and any masters

adding 1 line to the above code (i.e. removing the 1st blank) will result in a broken PowerPoint again, output attached (54.7 KB)

I’m wondering if the slide cloning bug fix (filed as SLIDESJAVA-38440) has inadvertently also fixed this issue? Not having access the the code I can’t say for sure if/why that would be so.

I am glad to inform you that the issues you described have already been resolved in Aspose.Slides 21.4. You should check it on your side.
