I can see my gameboard in the Scene View, but Game View appears black

I am following the rogue-like tutorial:

I have gotten through Level Generation #2 lesson fine, the board is randomly generated and I can see the sprite animated and the random game board generated in the Scene View when I click play, but the Game View appears black. I have added the Loader.cs script to the main camera and loaded the prefab’d GameManager to the loader script component of the main camera with still no luck. I tried adding a light to the main camera, still black.

What could cause the game board to be seen in Scene View, but cause the Game View to show only the color black?

@codesandkeys its is happeninh to me too. help
