What causes black spots on the face of images generated by models trained on my customer dataset？

this is artifacts it's normal when you're training gans

I used wav2lip_train.py for training. What I meant was that black dots appeared on the forehead of the face generated by the model, and black dots also appeared on the face during inference. I don't know how to avoid this problem.
