How can I use the while loop as a maintenance loop? (e.g.),How can I use the while loop as a maintenance-Loop? (e.g.)

   *void Start()
     {
         MaintenanceLoop();
         spawnVector = new Vector2(0, 0);
         playgroundSpawner = FindObjectOfType<PlaygroundSpawner>();
         blocksBehaviour = FindObjectOfType<BlocksBehaviour>();
 
         blockSpawner = GameObject.Find("BlockSpawner");
         if (!blockSpawner) 
         {
             blockSpawner = new GameObject("BlockSpawner");
         }
     }
 
     void Update()
     {
         playerVector.y = playgroundSpawner.playerPos.y;
     }
 
     public void MaintenanceLoop()
     {
         while(spawnVector.y == playerVector.y)
         {
             continue;
         }
         Spawn();
     }
 
     public void Spawn()
     {
         for (int i = 0; i < 15; i++)
         {
             if (spawnVector.y == playerVector.y)
             {
                 spawnVector.y += Random.Range(minSpawn, maxSpawn);
                 Vector2 currentPos = transform.position;
                 Vector2 yAdjusting = new Vector2(0, 0.5f);
                 int randValue = Random.Range(0, 3);
 
                 if (randValue >= 1)
                 {
                     GameObject SmallBlock = Instantiate(smallBlock, transform.position,
                         Quaternion.identity) as GameObject;
                 }
                 else
                 {

                 }
             }
             else
             {
                 MaintenanceLoop();
             }
 
             if (i >= 14)
             {
                 Difficulty();
                 i = 0;
             }
         }

             minSpawn--;
             maxSpawn--;
             blocksBehaviour.blockSpeed += 0.25f;
             MaintenanceLoop();*

My goal is that when the Player doesnt move the while Loop gets automatically called and works as an maintenance loop until it breaks when the spawnvector is equal the playerPos —> so the for loop can be executed the amount of times and so on
