It appears that all nude doll listings in every shop that I checked has the same "Item Not Available". You are unable to change the photo because you cannot access your own listing.

I wonder if it has to do with this announcement.

This is for children and not dolls but more than likely the bots see a nude doll and assume it's a child.
I think having Nude in the title is what is triggering it. I did a search for Nude in your shop and only 2 items showed up.
If you are unable to open the listing, see if you can go to your listings page, click Quick Edit and then remove the word Nude from the title there without opening the listing. Perhaps after you refresh that page you will be able to open it to change photos if you need to.
I hope I understood the question and I hope the above is of some help.
Results of my testing..... It appears to have something to do with thumbnails and body detention which it does not like. Zooming in via adjust thumbnail does not work, you have to actually crop the thumbnail image to remove as much 'body shape' as possible. Body shapes can exist in other images, but not the thumbnail. This explains the issues with so many items it swimwear/lingerie categories. If you change the thumbnail it should work
