(sorry for the late reply) It works now, but a green box flashes around the interaction point for a few seconds upon opening the program or switching costumes. It's not an issue as I said it is for a few seconds but you might want to do something about it or something.
The blinking green panel is intentional btw, to show where the interaction panel is. See https://kgm.itch.io/satania-buddy/devlog/635604/2023-11-14-character-importer
