View exact image/file that WP Smush Pro can't smush

Hello, I was using WP Smush Pro and I have a single image/file that was skipped due to an API: 500 Internal Server Error. I was wondering if there is a way to view what that file is? I've attached a screenshot for a better visual.

I've ran into other issues with my site and I think it is because of this file. I used Snapshot to try to backup (and I've tried other backup plugins) but there is something in my media that is giving me a similar error. Please let me know, thank you!!
