How to Fix weird AttributeError?

So I wanted to code a function for my game that switches the current state of the program and based on the current state, the menu that is displayed is a different one.

When I call the switch_to("Main_Menu"), i receive the following error:

File "d:\PythonProjects\MenuSystem\Menu.py", line 12, in switch_to
    for s in self.state.gamestates:
AttributeError: 'Game' object has no attribute 'gamestates'

It is a bit of code but really not complex at all. WHY is there an error with a Game Object when there is nothing done with a game object?

I tried so long to find out why this happens but im stuck at this problem... I hope you can help me.

Many thanks in advance !

This is the code from the main class:

game = Game()
    
gamestates ={
               0:  "Game",
               1:  "Main_Menu",
               2:  "Settings_Menu",
               3:  "Sound_Menu",
               4:  "Gamepause_Menu"
            }
state = State(gamestates, "Main_Menu")

main_menu = Main_Menu(game, state)
main_menu.switch_to("Settings_Menu") # THIS CAUSES THE ERROR

This is the State Object class:

class State:

    def __init__(self, gamestates: dict, current_state: str):
        self.gamestates = gamestates
        self.current_state = current_state

And lastly the Menu :

class Menu:

    def __init__(self, game, state: State):
        self.game = game
        self.state = state


    def switch_to(self, gamestate: str):
        for s in self.state.gamestates:

            if s == gamestate:
                self.state.current_state = gamestate
                return
        raise Exception("No gamestate named '" + gamestate + "'")
            
         
class Main_Menu(Menu):

    def __init__(self, game, state):
        super().__init__(self, game, state)
