Why does the renderer look normal but the actual game is pitch-black?

Godot Version

4.3 stable

Question

I was using godot trying to make something when I tried testing and my environment is pitch-black. I tried undoing, redoing things, deleting and re-implementing things but nothing works.

EDITOR:


GAME:

Have you add directional lighting and an environment to your scene? There are preview versions in the editor that won’t be in your running game.

In the editor it will not require an extra light source however in the game it will. Have you added a light source to the scene.
