Help with image distortion after using a background remover app.

I've used the background remover tool from both Adobe Express and Photoroom. However, when I then upload the resulting image to Illustrator, it shows up with the original background removed but with a distorted version of the image as well. Sometimes I can troubleshoot this by choosing to download the modified image to my files v. to my photos, but eventually neither work.

This is a new issue as of the past few months. I have otherwise used both apps/tools and the same process to do this successfully for months and months prior. Any insight is much appreciated!
