Top-Down Game. Player don't move while aiming

I can't move cursor while player is in move. Character must look at mouse and move. Pls help.

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class Shooting : MonoBehaviour
{ public Transform gun;

 public Rigidbody2D bullet;

 void Start()
 {
     GetComponent<Rigidbody2D>().angularVelocity = 0;
     float input = Input.GetAxis("Vertical");
 }
 void Update()
 {
     if (Input.GetButtonDown("Fire1"))
     {
         Rigidbody2D bulletClone;
         bulletClone = Instantiate(bullet, gun.position, gun.rotation) as Rigidbody2D;
     }
     Quaternion rotation = Quaternion.LookRotation(transform.position - Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector3.forward);
     transform.rotation = rotation;
     transform.eulerAngles = new Vector3(0, 0, transform.eulerAngles.z);
 }

}

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class PlayerMovement : MonoBehaviour { [SerializeField] float playerSpeed; [SerializeField] float playerWalkSpeed; [SerializeField] float playerRunSpeed; [SerializeField] float AccelerationFactor; [SerializeField] float walkDecelerationFactor; [SerializeField] float runDecelerationFactor; private Rigidbody2D rb; Vector2 movement;

 void Start()
 {
     rb = GetComponent<Rigidbody2D>();
 }

 // Update is called once per frame
 void Update()
 {
     movement.x = Input.GetAxis("Horizontal");
     movement.y = Input.GetAxis("Vertical");
 }
 void FixedUpdate()
 {
     RunSpeed();
     
     Vector2 move = rb.velocity = Vector2.Lerp(rb.velocity, movement * playerSpeed, AccelerationFactor / Time.fixedDeltaTime);
     rb.velocity = (move);
 }
 void RunSpeed()
 {
     if (Input.GetKey(KeyCode.LeftShift))
     {
         playerSpeed = playerRunSpeed;
     }
     else 
     {
         playerSpeed = playerWalkSpeed;
     }
 }

}
