No, this problem seems to be baked in to just this project. New projects are fine. Just wondering if there is a way to reset the Interface Preview.

I've made it to tutorial IV but there seems to be something messed up with my Interface Preview. It's blank, I mean totally blank with no keyboard, no ability to set the window size and no toolbar. Is there any way to reset it to the default? I checked some of the asset files but didn't see anything obvious. If I create a new blank project, the Interface Preview appears normal so it is something with this project.

This is running on OS X 10.13.3
