Just based on your screenshot, it looks OK. Can you explain what happens when you try to run it?
Also, if there is a GPU issue and it can’t detect the face then it can take a while to perform all of it’s retries. Then it should give up and move to the next image. It does 19 different face detection retried at different angle before it gives up. If you let it run for a minute or 2 does it eventually give up on the first image and move to the next image?
