Black square and a weird clipping in train SAEHD

[AGumman1]

Expected behavior

This is my first time doing something with deep fake and I'm using DeepFaceLab, I did all of the steps from extracting and face-set extracting and Xseg learning and applying the Xseg train then I start training my model using SAEHD train and this artifact start to show up and nothing like what I've seen on the internet.

I tried to clean the workspace and start over again and something happen.

Can anyone point out where the problem is?

And this is the tutorial that I was following with: DeepFace Lab Tutorial: How to make a DeepFake - YouTube
