Cant apply physics material.

So currently I am making a simple 2D game and when I move the player around he gets stuck to the walls. I saw somewhere that the solution was to add physics materials. So a I created one but somehow I cant add it to the collider, Because when I hover over the field Material on the Collider component, I just see a prohibited sign, that doest let me add it

Since you’re making a 2D game, make sure you’re using “Physics Material 2D”. This is found under Assets > Create > 2D > Physics Material 2D.
