The BoxCollider and CircleCollider2D interact with physics in different dimensions, box collider physics are calculated in 3D while circle collider physics are calculated in 2D. In Unity, 3D physics and 2D physics are calculated separately so collisions between 2D and 3D colliders isn’t possible. You will have to replace your box collider with a BoxCollider2D or replace your circle collider with a SphereCollider. Best of luck!
