Unwanted Character Controller Floating

As soon as I press play, my "CC" rises a few cm above the ground and just stays there. Here is what I did:

1. Start a new project

2. Create the ground (Cube)

3. Create the Player(Cube) + add Character Controller to the Player

4. Add this script to the Player

   public class PlayerMovement : MonoBehaviour {

     public float playerSpeed = 5.0f;
        CharacterController cc;
    
        // Use this for initialization
        void Start () {
            cc = gameObject.GetComponent<CharacterController> ();
        }
        
        // Update is called once per frame
        void Update () {
            Vector2 usrInput = new Vector2 (Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
    
            Vector3 moveDir = new Vector3 (usrInput.x, 0, usrInput.y);
            cc.Move (moveDir * Time.deltaTime * playerSpeed);
        }
    }
   
   
   

And I am having the floating issue already.

I did the same thing a few days earlier and it worked without any issues.
