this is another script

public class Arayuz : MonoBehaviour
{
    public GameObject esc;
   public bool tutorial = false;
    public GameObject oyunkontrol;
    public GameObject envanter;
    stopeverythin oyunkontrolscipt = new stopeverythin();
    // Start is called before the first frame update
    void Start()
    {
       
    }
    void envanteropen_close()
    {
        if (Input.GetKeyDown(KeyCode.Tab))
        {
            if (envanter.GetComponent<Animator>().GetBool("envanteropen") != true)
            {
                oyunkontrolscipt.durdur();
                envanter.GetComponent<Animator>().SetBool("envanteropen", true);
            }
            else
            {
                oyunkontrolscipt.baslat();
                envanter.GetComponent<Animator>().SetBool("envanteropen", false);
            }

        }
    }

It looks like you are calling the method Baslat recursively so it is just constantly running through it. Try calling it once.

I don’t see where you have recursion, but @davidnibi is almost certainly correct.

If you are just looking to pause the game, why not just set Time.timeScale = 0.0f; ?
