Unity GameObject.SetActive doesn't not work

Question

I wrote for my Game a Script that controls the Slots in the game by GameObject. But the script isn't able to activate or deactivate. Everything is set up as it should, I also tried another Script but that works. The "main" script doesn't.

Here is the code:

    // Update is called once per frame
    void Update()
    {
        UpdateBools();
        Crosshair();
        Slots();
    }
    void UpdateBools()
    {
        isPaused = PauseMenu.GamePaused;

    }
    public void Crosshair()
    {
        //Not important
    }
    public void Slots()
    {
        if (database.Slot1 != nothing)
        {
            Slot1.SetActive(true);
            Slot1Active = true;
        }
        else { Slot1.SetActive(false); }
        if (database.Slot2 != nothing)
        {
            Slot2.SetActive(true);
            Slot2Active = true;
        }
        else { Slot2.SetActive(false); }
        if (database.Slot3 != nothing)
        {
            Slot3.SetActive(true);
            Slot3Active = true;
        }
        else { Slot3.SetActive(false); }
        if (database.Slot4 != nothing)
        {
            Slot4.SetActive(true);
            Slot4Active = true;
        }
        else {
            Slot1.SetActive(false);
            Slot2.SetActive(false);
            Slot3.SetActive(false);
            Slot4.SetActive(false);
            Slot1Active = false;
            Slot2Active = false;
            Slot3Active = false;
            Slot4Active = false;
        }
    }
    public void SlotPic()
    {
        //I erased this because stack overflow says: mostly code, add more details but I have every detail
    }

It works like this: If one inventory slot is taken, it should be activated. For testing, I added ActivateEverything(). Also, the slot should change its picture when activated but as I said, activating the object doesn't work. Important for this task is the void Slots().

Try to setActive without if else containers. Check if your gamemode not on pause.
