Why the lightning suddenly change?

I have a problem in my unity project that is when I change one scene from another, the scene suddenly turns dark. So this is before:

And after switch from the main menu to this scene:

[GNPhoque]

Check in Window > Rendering > Lighting
you should have a Lighting Settings selected (if None, click New Lighting Settings) and check in the bottom that auto-generate is ticked off then click Generate Lighting.
This has to be done for every scene from what I saw.
