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 *== true && isSelected[j] == true)*

{
Temp = Peçass*;*
Peçass = 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().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 = 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 == true && isSelected[j] == true)
{
Temp = Peçass*;*
Peçass = Peçass[j];
Peçass[j] = Temp;
}
}
}
howManySelected = 0;
}
The Unity version I’m using is 2020.2.2f1
Thank you!

It might be this line: for (int j = i + 1; i < isSelected.Count; j++). I believe it should be for (int j = 1; j < isSelected.Count; j++)

The reason this causes a crash, is because your for loop never ends. It ends when i is less that isSelected.Count, however, i is never incremented in the for loop. Only j is. Therefore the loop will never end. @DiasPTW
