Transparent objects in only one scene and no buttons work?

As you can see here, somehow everything has gone transparent and even in play mode it is the same.
No other scenes have this issue. I was thinking it was something to do with the camera. I am very fresh to the Unity interface so I am a tad lost and been clicking random buttons for hours. lol. Any ideas what I have done?

  1. Are you using Materials on UI elements?
    E.g. Main Camera > Canvas > Image > Image Component > Material.
    If so, set to None and check.

  2. Is there any reason to make Main Camera as a parent of Canvas?
