hello everyone im trying to make a 2d topdown game in unity and the script i wrote isn't working

using UnityEngine;

public class TopDownPlayerMovement : MonoBehaviour
{
    public float moveSpeed = 5f;     

    private Vector2 moveInput;       
    private Vector2 movement;        

    void Update()
    {
        moveInput.x = Input.GetAxisRaw("Horizontal"); 
        moveInput.y = Input.GetAxisRaw("Vertical");  
        if (moveInput.magnitude > 1)
        {
            moveInput.Normalize();
        }

        movement = moveInput * moveSpeed;
      
        transform.Translate(movement * Time.deltaTime, Space.World);
    }
}

using UnityEngine;

public class TopDownPlayerMovement : MonoBehaviour
{
    public float moveSpeed = 5f;     

    private Vector2 moveInput;       
    private Vector2 movement;        

    void Update()
    {
        moveInput.x = Input.GetAxisRaw("Horizontal"); 
        moveInput.y = Input.GetAxisRaw("Vertical");  
        if (moveInput.magnitude > 1)
        {
            moveInput.Normalize();
        }

        movement = moveInput * moveSpeed;
      
        transform.Translate(movement * Time.deltaTime, Space.World);
    }
}
