Crush player with moving wall

I have a player (Ball) and a moveable cube. If i push the player into a wall with the cube I want the player to get crushed. I also don't want a menu if the player dies. I want the whole scene to immediately reset as soon as the player dies. t$$anonymous$$s is my script for the player:`

 using UnityEngine;
 
 public class MoveWithForceWASD : MonoBehaviour
 {
     private Rigidbody _rigidbody;
 
     [SerializeField] private float _movementForce = 10f;
 
     private void Awake() => _rigidbody = GetComponent<Rigidbody>();
 
     private void FixedUpdate()
     {
         if (Input.GetKey(KeyCode.W))
             _rigidbody.AddForce(_movementForce * Vector3.forward);
 
         if (Input.GetKey(KeyCode.S))
             _rigidbody.AddForce(_movementForce * Vector3.back);
 
         if (Input.GetKey(KeyCode.D))
             _rigidbody.AddForce(_movementForce * Vector3.right);
 
         if (Input.GetKey(KeyCode.A))
             _rigidbody.AddForce(_movementForce * Vector3.left);
     }      
 }

and t$$anonymous$$s here is my script for tha moveable cube:

 using UnityEngine;
 public class TestScriptFromUnityAnswers2 : MonoBehaviour
 {
     private Rigidbody _rigidbody;
     public bool _canChangeDirection;
     private Vector3 _direction;
     [SerializeField] private float _movementForce = 10f;
 
     public void Awake()
     {
         _rigidbody = GetComponent<Rigidbody>();
         _canChangeDirection = true;
     }
 
     private void Update()
     {
         if (_canChangeDirection)
         {
             if (Input.GetKeyDown(KeyCode.UpArrow))
                 SetForceDirection(Vector3.forward);
 
             if (Input.GetKeyDown(KeyCode.DownArrow))
                 SetForceDirection(Vector3.back);
 
             if (Input.GetKeyDown(KeyCode.RightArrow))
                 SetForceDirection(Vector3.right);
 
             if (Input.GetKeyDown(KeyCode.LeftArrow))
                 SetForceDirection(Vector3.left);
         }
     }
 
     private void FixedUpdate()
     {
         if (_direction.sqrMagnitude > 0.01f)
             _rigidbody.AddForce(_movementForce * _direction);
     }
 
     private void SetForceDirection(Vector3 direction)
     {
         _direction = direction;
         _canChangeDirection = false;
     }
 
     void OnCollisionEnter(Collision col)
     {
         if (col.gameObject.name == "Wall")
         {
             _canChangeDirection = true;
             _direction = Vector3.zero;
         }
     }
 }
