Unity camera only showing blue in fourth scene.

Hi guys, I have been making a game and I have had a big issue. But I have ran into an issue.

I have just made the fourth Scene, and when I put the player prefab into the level and all I could see it blue on the cam. Anyone had this before?

It is strange, I have not had it before.

I have the player in a prefab, Is that causing the issue?

could you give any capture?
