Question How can I hide clipping?

Hello everyone! I am making a top down game where everywhere is pitch black other than the map itself. The solution that I did was to make the world dark and give the walls a backface with a pitch black material with it. However when the player moves to the corner like this, it clips through the wall. How can I hide this clipping? I am using URP and I tried playing around with Render Objects however I couldn't make it work.

Here is a picture of player clipping in the corner:
