UD v4 - creating a new app fails without modifying/adding/deling what was produced by UD itself

I have UD V4.0.2

When I go to Apps and create a new app, based on the multi page template, the app never runs.
I never touched any of the components or pages or settings, I just created the TestApp and try to run it/view it.

The View App results:
