My box collider 2d isn't supporting the player

So the player passes right though the object even when the box collider 2d is applied!! I tried making a new object and deleting the old one, but it still won’t work, pls help :(((

One of your elements (Player and the colliding object) must have an Rigidbody2D assigned, that they are able to collide. Also ensure both colliders are not marked as triggers.
