object reference not set to an instance of an object

Unity Engine

I am having trouble running my code in unity. Whenever my player collides into an obstacle it should restart the game. However, it comes up with the error ‘Object reference not set to an instance of an object’. The first picture is the error that I come across. The second picture is my GameMnager script and the third is my PlayerColision script.

Did you attach the GameManager script to a GameObject in the scene?
