Why this AI image was rejected?

I've uploaded a few wallpaper images that were accepted while others, along the same lines, were not. It's not worth obsessing over. And if you're going to do images that only have commercial value as wallpapers or graphic assets, do a 16:9 ratio. This looks more liek 10:8.

Is this the original size?

As others have said, compression artifacts seem to be a big problem.

With AI, you really need to go through the image with a fine toothcomb. There can be a whole heap of reasons. Just because one got accepted and this was rejected, does not mean that this should be accepted. Perhaps the other should have been rejected.

As with your other posts: tell us the rejection reason, upload the original file(s) as submitted. You should check your assets before submission at 100% and 200% to detect artefacts.
