Animated Chest (the animation while the gui is open does not stop running when closing it)

As I mentioned in the title, I have the problem that when opening the chest, it executes the animation "1" which is the animation in which it shows the chest opening, then it executes the animation "2" which is the animation in which the chest remains open, however when I close the GUI, the animation "3" does not run, I have suspicions that it may be because the animation "2" is a Loop, can someone give me advice or help me to solve it?
