I'm facing a similar issue, the review of my application returned with an error that occurs on iPad iOS 16.5.1, but this version is not available for testing. I need it to proceed with the app submission.

Worked for me on March 2024 :)

I faced the same problem. For me, the solution was to 're-convert' the image. For example, I had an image in a format specific to the store. I went to a website that converts images to pixels and converted it. Then, I saved and uploaded it to the store again. After that, I reloaded the page and it worked!
