When I add a static camera I can't move my Pawn

I’m learning Unreal Engine and I have followed this tutorial. And I can move my Pawn.

But now I’m trying to add a new camera removing the one from the Pawn. I have followed this tutorial. Adding a static camera and now I can’t move my object. Why?

If I remove the camera attached to the Pawn it moves.

I have uploaded my project to GitHub.
