Empty Game Window

Hi everyone, for some reason my Game Window is Empty, and when I Play whats on my scene, is still empty is not showing anyting, it was working well when I started this morning, but not really sure if I clicked somewhere. My game works perfectly on the Scene Window
Any reason why? Thanks!

Could be a lot of reasons why this is happening. Once place to start it to check your camera inspector. If you working in 2D, make sure it is active, that it an orthographic camera and it is pointed in the right direction; that the clipping planes are set appropriately. That you objects are in a layer that actually gets rendered.

like said streeetwalker lot of stuff can do this…
Did u tryed to go to the Inspector windows while runtime and see the cam’s pos,rotation,layer,etc…
