Game View Turns Gray During Playtest

I have a strange situation that is stumping me. I am making a 2D platformer in 3D space. Up until today it has been going smoothly. Over the past few hours whenever I click play to test my game/mechanics it will randomly turn solid gray. I noticed this happens in only a few areas, or if the character is idle. There is nothing between the character and the camera, and moving around doesn’t fix it.

I am using Unity 4.6.1f1 and Playmaker 1.7.7.2

There isn’t anything in playmaker that affects the camera, and the camera is a child of the character.

Many thanks.

I am having the same problem but I am using unity 2020
