Regarding the default "Depth" value of [Main Camera]

[Joseph-Park-dev]

If you open up a project and press the run button on Unity editor, after loading screen the background of the title menu turns black and even though I press the play button, nothing except for the UI elements can be seen, which makes the game unplayable.
In the inspector menu of the object [Main Camera], there should be a slot named "Depth" whose value is set to -1. I tried to modify it and found that setting the value bigger than 2.1 makes the game objects visible. But this made another problem that in the title menu UI elements are placed behind the game objects and the RedRunner is floating in the air (seemingly an initial position).

I faced this issue while opening this in Unity 2019, Unchecking the "Directly to Camera Target" option on the Post Processing Layer component under Main Camera inspector settings worked for me.
