Can't view the map in-game

Hi! I’m really new to Ark Dev Kit, but I’ve followed this tutorial and I’m at point where I have small island with water around it.

I decided to try it in-game, but the dev kit freezes when I press the play button. I waited for 15 mins, but nothing happens. I tried opening it in standalone game, I’ve adjusted graphic settings to low, but it doesn’t help either. This problem exists also in the default level which loads when you open dev kit.

What could I do?

Did you do this ?
