ValueError: zero-size array to reduction operation maximum which has no identity

[Dean-Corso]

Describe the bug
"Face Swap frames" isn't working. I get that error "ValueError: zero-size array to reduction operation maximum which has no identity" every time I press on refresh button when I have this option checked.

Does this also happen when using "First found" or any other face selection mode?

[Dean-Corso]

It happens all the time with any selection type when I have checked the "Face swap frames" checkbox. It was working correctly in the version 3.5.0 I used before. Otherwise the Start button does work to process the face swap to show the final image below. Only the preview window above it's working with the enabled Face swap option and it does always print that error "zero-size array".

I also have an issue with the manual masking feature. When I press on "toggle manual masking" then the loaded image in the preview window does disappear and I just see some new small buttons for paste, image button, draw button & erase button but how to use them when no image is showing anymore? Is this a bug? Otherwise if I do anything wrong then you could maybe tell us how to use it.

I also tried the text mask feature which was not working for me in the older 3.5.0 version. This time it seems to work to mask something on the image like "hair" or "glasses" but in case of other objects it does fail and just showing a full black image. I even can not mask anything manually on the image because it's when gone when I press on toggle manually masking as I said above.
