My unity STOPS RESPONDING when this function is activated

So whenever I click play everything is fine however when I do something that calls this function:

 void SwapCards()
     {
         string Temp = "tmp";
         for (int i = 0; i < isSelected.Count; i++)
         {
             for (int j = i + 1; i < isSelected.Count; j++)
             {
                 if (isSelected[i] == true && isSelected[j] == true)
                 {
                     Temp = Peçass[i];
                     Peçass[i] = Peçass[j];
                     Peçass[j] = Temp;
                 }
             }
         }
         howManySelected = 0;
     }

the Unity engine stops responding. I've tried to comment this function out and the engine keeps running fine so this one is definitely the problem. What can I do to fix this?

Here's all the code where this function is involved for better context:

 private void Update()
     {
         TimeStep = FindObjectOfType<GridCreation>().timeStep;
         if (Input.GetKeyDown(KeyCode.P))
         {
             canMove = !canMove;
         }
 
         if (canMove)
         {
             if (!isRunning)
             {
                 StartCoroutine(AplicarMovimento());
             }
             
         }else { StopCoroutine(AplicarMovimento()); isRunning = false; }
         if (howManySelected == 2)
         {
             SwapCards();
         }
         AbrirHotbar();
         FillImages();
     }
 
 public void OnPointerClick(PointerEventData eventData) //Deteta os "clicks" no UI
     {
         for (int i = 0; i < Peçass.Count; i++)
         {
             Transform carta = Hotbar.transform.GetChild(i);
             if (carta == eventData.pointerCurrentRaycast.gameObject.transform)
             {
                 isSelected[i] = true; //A carta onde deu click fica "selecionada"  
                 howManySelected++;
             }
         }
     }
 
     void SwapCards()
     {
         string Temp = "tmp";
         for (int i = 0; i < isSelected.Count; i++)
         {
             for (int j = i + 1; i < isSelected.Count; j++)
             {
                 if (isSelected[i] == true && isSelected[j] == true)
                 {
                     Temp = Peçass[i];
                     Peçass[i] = Peçass[j];
                     Peçass[j] = Temp;
                 }
             }
         }
         howManySelected = 0;
     }

The Unity version I'm using is 2020.2.2f1

Thank you!
