Texture stream in request failed due to IO error (Mip 0-2)

Whenever I try to publish a private version of my UEFN map it gives me a validation error saying “Texture stream in request failed due to IO error (Mip 0-2)”. That text also keeps on looping forever in my output log. I was just wondering if there’s any way to fix this?
