Image Sizes/Thumbnails not generating on local install Ampps

I’m not sure what is going on. I can’t get the thumbnails to generate. I tried the “force regenerate thumbnails” plugin, but that didn’t work.

I’ don’t have any plugins running and I’ve tried with a fresh functions.php file, but still nothing. I’m using genesis framework with a custom child theme (which is pretty bare bones currently)

Is there some settings I can try in the php.ini or elsewhere? I’m thinking that has something to do with the server rather than wordpress. Just don’t know where to start.
