Help me Please, if I can’t fix this I will have to start over.

When I press play, to play in an editor window it dosent allow me to do this.

I can play the game if I go into the finder and click on the project, it will launch outside of the editor and work just fine.

Other than this, I literally cannot playtest my game at all. Can still edit just fine.

What I believe caused this was when I duplicated my game and then deleted the duplicant.

Please help. Included are screenshots.
