Hello,
We are currently using Aspose Slides 17.6 and we have a presentation template that throws an exception when we try to save it as PPTX. The exception message is “An entry with the same key already exists.”
I tried updated to the latest version (18.11) but in my case it doesn’t fix the issue. I’ve attached a stripped version of the template that still throws the exception
