Unity Freeze when im using while timer

Question

Hello. When i try run this script it freezes unity.

I read about this problem it is problem when while loop is infinite but in my case it isnt.

I use this code in update function.

Thanks for answers :)

Code Here:

for (int i = 0; i < max; i++){

             while (wait > 0)
             {
                 Debug.Log("-");
                 wait -= Time.deltaTime;//decressing timer
             }
             food.GetComponent<SpriteRenderer>().color = Color.gray; //set color
             food.transform.position = Random.insideUnitCircle + new Vector2(transform.position.x, transform.position.y); //set positions
             Instantiate(food); //create gameobject
             count++;
             wait = 100; //setting it back up
         }
