my editor freezing when pressing play button

I was making a racing game for my project, and suddenly, when I pressed play button, unity freezes! I don`t think it is a infinite loop because last time with my while loop, everything was great... I can`t do my unity project for days now. I tried everything. fixing the codes... changing tags.. anyway, here`s my only and ultimate code in my game(has racing, accelerlate, powerups) it`s not finished yet, and I need to add another code to manage the game. using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class movereal : MonoBehaviour {
     public int speed;
     public int rawspeed;
     public int rotate;
     public int speedup;
     public GameObject GameObje1ct;
     // Use this for initialization
     void Start () {
         rawspeed = rawspeed + speedup;
         speed = speed + speedup;
 
         while(speedup < 48)
         StartCoroutine (speedUp ());
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetKey (KeyCode.W))
             transform.Translate (Vector3.forward * speed * Time.deltaTime);
 
         if (Input.GetKey (KeyCode.S))
             transform.Translate (Vector3.back * speed * 0.3f * Time.deltaTime);
 
         if (Input.GetKey (KeyCode.A))
             transform.Rotate (Vector3.up * -rotate * Time.deltaTime * 2.5f);
 
         if (Input.GetKey (KeyCode.D))
             transform.Rotate (Vector3.up * rotate * Time.deltaTime* 2.5f);
 
         if (Input.GetKey (KeyCode.LeftShift))
             transform.Rotate (Vector3.up * -rotate * Time.deltaTime);
 
         if (Input.GetKey (KeyCode.F))
             transform.Rotate (Vector3.up * rotate * Time.deltaTime );
 
         if (Input.GetKey (KeyCode.Space))
             speedup = 0;
 
             }
     void OnTriggerEnter(Collider other)
     {
         if (other.gameObject.CompareTag ("boost")) {
             speed = speed + 10;
         }
         {
             if (other.gameObject.CompareTag ("noboost"))
                 speed = rawspeed;
             
     }
         {
         if (other.gameObject.CompareTag ("gb"))
         speed = speed + 25;
     }
 
 
 
         if (other.gameObject.CompareTag ("wall:"))
             speedup = 0;
 
 
 }
     IEnumerator speedUp()
     {
         yield return new WaitForSeconds(2.5f);
         speedup = speedup + 4;
         yield return new WaitForSeconds (2.5f);
         speedup = speedup + 4;
     
 
 }
 }
