How can I fix this movement?

PBIX

This is based on BMo's 5-minute top down shooter, I'm trying to add a dash but for some reason it cancels out the wasd movement so I can only move with the dash. There are no errors in Unity, does anyone know how to fix this? (IDK how to properly copy paste my code)

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class PlayerController : MonoBehaviour

{

   public float moveSpeed = 5f;

   public Rigidbody2D rb;

   public Weapon Weapon;

   public float dashSpeed = 200000;

   public Rigidbody2D rg;

   bool dash = true;

   int dashCooldown = 80;

   Vector2 moveDirection;

   Vector2 mousePosition;

   void Start()

   {

   }

   void Update()

   {

       float moveX = Input.GetAxisRaw("Horizontal");

       float moveY = Input.GetAxisRaw("Vertical");

       if(Input.GetMouseButtonDown(0))

       {

           Weapon.Fire();

       }

       if(Input.GetKeyDown(KeyCode.R))

       {

           Weapon.Reload();

       }

       moveDirection = new Vector2(moveX, moveY).normalized;

       mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);

       }

   private void FixedUpdate()

   {

       rb.velocity = new Vector2(moveDirection.x * moveSpeed, moveDirection.y * moveSpeed);

       Vector2 aimDirection = mousePosition - rb.position;

       float aimAngle = Mathf.Atan2(aimDirection.y, aimDirection.x) * Mathf.Rad2Deg - 90f;

       rb.rotation = aimAngle;

       if (dashCooldown == 0)

       {

           dash = true;

       }

       else

       {

           dashCooldown--;

       }

       rg.velocity = Vector2.zero;

       if (dash && Input.GetKey(KeyCode.Q))

       {

           Vector2 mouseDirection = (Input.mousePosition - new Vector3(Screen.width / 2, Screen.height / 2)).normalized;

           rg.AddForce(mouseDirection * dashSpeed * Time.fixedDeltaTime);

           dash = false;

           dashCooldown = 80;

       }

   }

}
