Thank you for the quick answer. I tested with and the issue is no longer occurring.

I noticed that if I delete the “picture box” object from my worksheet, I can also make it work with previous versions of Aspose, can you provide some insight in this? Is it a specific type of picture box that is causing this error? Or all pictures? I would like to give a “workaround” solution for my product which is not yet using the latest version.
