I also have the image field not working in 5.0.8
But it’s not on an Options page. It’s on a Custom Post Type edit screen.
This:
“as soon as I press ‘select’ in the wordpress media manager, it just won’t insert the image. The field still says ‘Add Image’”
So maybe this issue effects more than just Options pages.
Console shows:
Uncaught Error: A "url" property or function must be specified
