Player rotating after wall collision

Hello,

I have a game in which the player can Press W to move forward and A & D to rotate. Tthe problem I have is that once it hits a wall on it's side it starts rotating uncontrollably until i hit it again on the front. Please help if you can, im open to everything. Here is my movement script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class movement : MonoBehaviour {
 
     public Rigidbody2D player;
     public float speed;
     public float rotSpeed;
     public GameObject wall;
     public float delay;
 
     private bool movementEnabled = true;
 
 
     // Use this for initialization
     void Start () {
         player = GetComponent<Rigidbody2D>();
         wall = GetComponent<GameObject>();
     }
 
     IEnumerator timeDisabled ()
     {
         yield return new WaitForSeconds(delay);
         movementEnabled = true;
     }
 
     void OnCollisionEnter2D(Collision2D wall)
     {
         movementEnabled = false;
         StartCoroutine("timeDisabled");
     }
 
     void RotateLeft()
     {
         transform.Rotate(Vector3.forward * rotSpeed);
     }
 
     void RotateRight()
     {
         transform.Rotate(Vector3.back * rotSpeed);
     }
 
     void move()
     {
         if (Input.GetKey(KeyCode.W))
         {
             player.velocity = (transform.up * speed);
         }
         else
         {
             player.velocity = new Vector2(0, 0);
         }
 
         if (Input.GetKey(KeyCode.A))
         {
             RotateLeft();
         }
         if (Input.GetKey(KeyCode.D))
         {
             RotateRight();
         }
     }
 
     // Update is called once per frame
     void Update () {
         if (movementEnabled == true)
         {
             move();
         }
         else
         {
 
         }
         
     }
 }
 

Thank you!
