Respawned playerprefab unable to control ,Player death and respawn, but playerprefab unable to control or move

Hi...I have followed "The Life of Pottsy" video and steps to respawn player after the player has die. However, after respawned the player cannot control (i.e. no movement (left, right, up or down) even I try to control using the keyboard). How do I resolved this.

Below is the script for the player

public class SqScript : MonoBehaviour { public float bodyforce; public float bobspeed; public float jumpspeed;

 // Update is called once per frame
 void Update()
 {
     // Key down press right & left movement
     if (Input.GetKeyDown(KeyCode.D))
     {
         transform.GetComponent<Rigidbody2D>().AddForce(Vector3.right * bodyforce);
         transform.Translate(Vector3.right * bobspeed * Time.deltaTime);
     }

     else if (Input.GetKeyDown(KeyCode.A))
     {
         transform.GetComponent<Rigidbody2D>().AddForce(Vector3.left * bodyforce);
         transform.Translate(Vector3.left * bobspeed * Time.deltaTime);
     }

     // Key down press jump movement, up and down
     if (Input.GetKeyDown(KeyCode.W))
     {
         transform.GetComponent<Rigidbody2D>().AddRelativeForce(Vector3.up * bodyforce);
         transform.Translate(Vector3.up * jumpspeed * Time.deltaTime);
     }

     else if (Input.GetKeyDown(KeyCode.S))
     {
         transform.GetComponent<Rigidbody2D>().AddForce(Vector3.down * bodyforce);
         transform.Translate(Vector3.down * bobspeed * Time.deltaTime);
     }
     
 }

}

Below is the Player Death script public class PlayerDeath : MonoBehaviour {

 void OnCollisionEnter2D(Collision2D collision)
 {
          
         if (collision.gameObject.CompareTag("enemywhite"))
         {
             Destroy(gameObject);
             print("Player Killed");

             // Heartcounter.health -= 1;
             print("Collided");       

             LevelManager.instance.Respawn();

         }       
 }

}

Below is the LevelManager script

public class LevelManager : MonoBehaviour {

public static LevelManager instance;

public Transform respawnPoint; public GameObject playerPrefab;

private void Awake() { instance = this;

}

public void Respawn() { Instantiate(playerPrefab, respawnPoint.position, Quaternion.identity); }

}

Please help...thanks.

,I have followed "The Life of Pottsy" video and copy his code when the player is killed, it will respawn. The code went well and respawned. But the respawn playerprefab is unable control or move. How do I resolved this.

Below is the code

PLAYER CODE Below

public class SqScript : MonoBehaviour { public float bodyforce; public float bobspeed; public float jumpspeed;

 // Update is called once per frame
 void Update()
 {
     // Key down press right & left movement
     if (Input.GetKeyDown(KeyCode.D))
     {
         transform.GetComponent<Rigidbody2D>().AddForce(Vector3.right * bodyforce);
         transform.Translate(Vector3.right * bobspeed * Time.deltaTime);
     }

     else if (Input.GetKeyDown(KeyCode.A))
     {
         transform.GetComponent<Rigidbody2D>().AddForce(Vector3.left * bodyforce);
         transform.Translate(Vector3.left * bobspeed * Time.deltaTime);
     }

     // Key down press jump movement, up and down
     if (Input.GetKeyDown(KeyCode.W))
     {
         transform.GetComponent<Rigidbody2D>().AddRelativeForce(Vector3.up * bodyforce);
         transform.Translate(Vector3.up * jumpspeed * Time.deltaTime);
     }

     else if (Input.GetKeyDown(KeyCode.S))
     {
         transform.GetComponent<Rigidbody2D>().AddForce(Vector3.down * bodyforce);
         transform.Translate(Vector3.down * bobspeed * Time.deltaTime);
     }
     
 }

}

PLAYER DEATH CODE Below

public class PlayerDeath : MonoBehaviour {

 void OnCollisionEnter2D(Collision2D collision)
 {
          
         if (collision.gameObject.CompareTag("enemywhite"))
         {
             Destroy(gameObject);
             print("Player Killed");

             // Heartcounter.health -= 1;
             print("Collided");       

             LevelManager.instance.Respawn();

         }       
 }

}

LevelManager CODE below

public class LevelManager : MonoBehaviour {

public static LevelManager instance;

public Transform respawnPoint; public GameObject playerPrefab;

private void Awake() { instance = this;

}

public void Respawn() { Instantiate(playerPrefab, respawnPoint.position, Quaternion.identity); }

}
