Vector2 Reflect works only in some cases

Hi all,

I am trying to add a feature in my 2D top-down game where when the player hits a wall while dashing to bounce off from it in a reflective manner:

I am using rigidbody2D and boxcollider2d for the player and for the wall - tilemapcollider2d, rigidbody2d compositecollider2d.

I've implemented a way to do it, but it only works in some cases:

*the right wall, when I am coming from bottom and right

*the bottom wall, when I am coming from top and left, but only for part of the wall

I don't understand why it doesn't work 100%. It seems like it changes the reflection based on where the player is in the box. The code I have used is this (in fixed update):

 public class PlayerMovement : MonoBehaviour
 {
 
     public float movementSpeed;
     public Rigidbody2D rigidBody2D;
     private Vector2 movementVector;
     private Vector2 mousePosition;
     public Camera cam;
     
     //dashing properties
     public bool isdashing = false;
     private float dashTime;
     private bool canDash = true;
     public float dashCooldown;
     public float movementSpeedDashMult;
     public float dashingTime;

     private bool hasHitWall=false;
     private Collider2D playerColl;
     private Collider2D wallColl;
     private Vector2 movementVectorForDash;
 
     void Start() {
         playerColl = GetComponent<BoxCollider2D>();
         wallColl = GameObject.Find("Grid/Walls").GetComponent<CompositeCollider2D>();
     }
 
 
     void Update() {
         movementVector.x = Input.GetAxisRaw("Horizontal");
         movementVector.y = Input.GetAxisRaw("Vertical");
    
         mousePosition = cam.ScreenToWorldPoint(Input.mousePosition);
 
         if(Input.GetKeyDown(KeyCode.Space)){
             StartCoroutine(Dash());
         }
     }
 
     void FixedUpdate() {
         if(isdashing) {
             dashTime -= Time.deltaTime;
             if(dashTime >= 0) {
                 if(playerColl.IsTouching(wallColl)) {
                     RaycastHit2D[] hitInfo = Physics2D.RaycastAll(transform.position,movementVector.normalized,1f);
                     for(int i = 0;i<hitInfo.Length;i++) {
                         if(hitInfo[i].collider.name == "Walls") {
                             movementVectorForDash = Vector2.Reflect(movementVector.normalized,hitInfo[i].point);
                             break;
                         }
                     }
                     hasHitWall=true;
                 }
 
                 if(hasHitWall) rigidBody2D.MovePosition(rigidBody2D.position + movementVectorForDash.normalized * movementSpeed * movementSpeedDashMult * Time.fixedDeltaTime);
                 else rigidBody2D.MovePosition(rigidBody2D.position + movementVector.normalized * movementSpeed * movementSpeedDashMult * Time.fixedDeltaTime);
                 
             } 
             else {
                 isdashing=false;
                 hasHitWall=false;
                 GetComponent<TrailRenderer>().emitting=false;
             }
         }
         else {
             rigidBody2D.MovePosition(rigidBody2D.position + movementVector.normalized * movementSpeed * Time.fixedDeltaTime);
         }
 
         Vector2 lookingDirection = mousePosition - rigidBody2D.position;
         float angle = Mathf.Atan2(lookingDirection.y,lookingDirection.x) * Mathf.Rad2Deg-90f;
         rigidBody2D.rotation = angle; 
     }
 
     IEnumerator Dash() {
             if(canDash){
                 GetComponent<TrailRenderer>().emitting=true;
                 FindObjectOfType<AudioManager>().playSound("dash");
                 //dashEffect.SetActive(true);
                 //cam.GetComponent<Animator>().SetTrigger("shakeIt");
                 dashTime=dashingTime;
                 isdashing = true;
                 canDash=false;
                 //yield return new WaitForSeconds(0.6f);
                 //dashEffect.SetActive(false);
                 //yield return new WaitForSeconds(dashCooldown-0.6f);
                 yield return new WaitForSeconds(dashCooldown);
                 canDash=true;
             }
     }
