I downloaded your experience, replaced the Launch Application path for my magick.exe process to be found and your XP worked for me out of the box.
The new image should be generated in the same folder saves the snapshot.

Copy it in your Windows File Explorer remove the file name to check what’s inside that folder. Do you see the “_flop” images there?
