Image Occlusion Enhanced constantly closing

Does anyone know what could be the problem here. I have tried all of the steps but it doesn’t seem to work.

Everytime I try to open an image on image occlusion advanced the app sends me back tot he home - screen of my mac.

When I return to the anki page, sometimes the picture is there and it lets me continue to make the card as normal. But as I click “Hide all guess one” to make the card the following text appears:

Error
