Face Transfer failed to generate. Try a different source image

Just as the subject displays, this is the error/message that I am receiving when I try to apply the following images

Before somone asks - Windows 11 Pro - 12th Gen Intel(R) Core(TM) i9-12900K, 3200 Mhz, 16 Core(s), 24 Logical Processor(s) - Asus ProArt Z690-CREATOR WIFI - Daz Studio 4.20

I am trying to apply this to G8M. I have also tried on G8F but the same notification appears

I have also loaded the CC Avandrael character, which is literally a female devil and I still receive the same notification in trying to use Face Transfer

As some of you probably know from my renders on Insta, I have been doing face transfers for a while, so why isn't this one working

I would appreciate any insight on this issue

Thanks in advance
