Every attempt to get Dalle to create a photo of a fictional alien person fails

I keep getting

Error creating image

I apologize for the repeated issues with the image generation. It seems we’re unable to create the image at this time. If there’s anything else I can do for you, please let me know.

It only does this when I ask it to create a human, or a human like person. I have tried incredibly detailed descriptions or incredibly brief ones. It has no problem when I ask it to create a photo of a Sun smiling down on a field of knives, so I am unsure as to why this could be. It doesn’t say it is content related and the images I am asking it to create aren’t even of real people or a based on a person. Has been happening for days
