React native – The action 'NAVIGATE' with payload {"name":"Game","params":{"roomId":"…"}} was not handled by any navigator

I am creating a game in react-native (typescript) using firebase, but I encounter this error while adding a "Game" screen:

I have this code for my App.tsx :

import React, { useEffect, useState } from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';

import Login from './app/screens/Authentication/Login';
import Register from './app/screens/Authentication/Register';
import Home from './app/screens/Home/Home';
import Game from './app/screens/Game/Game';
import { FIREBASE_AUTH } from './FirebaseConfig';

const Stack = createNativeStackNavigator();

export default function App() {
  ...

  return (
    <NavigationContainer>
      <Stack.Navigator>
        {user ? (
          <Stack.Screen
            name="Home"
            component={Home}
            options={{ headerShown: false }}
          />
        ) : (
          <>
            <Stack.Screen
              name='Login'
              component={Login}
              options={{ headerShown: false }}
            />
            <Stack.Screen
              name='Register'
              component={Register}
              options={{ headerShown: false }}
            />
            <Stack.Screen
              name='Game'
              component={Game}
              options={{ headerShown: false }}
            />
          </>
        )}
      </Stack.Navigator>
    </NavigationContainer>
  );
}

And here is the part of my types.tsx file :

import { StackNavigationProp } from '@react-navigation/stack';

// Navigation
type RootStackParamList = {
    Home: undefined;
    Login: undefined;
    Register: undefined;
    Game: { roomId: string | null };
}

export type HomeNavigationProp = StackNavigationProp<RootStackParamList, 'Home'>;
export interface HomeProps {
    navigation: HomeNavigationProp;
}
export type RegisterNavigationProp = StackNavigationProp<RootStackParamList, 'Register'>;
export interface RegisterProps {
    navigation: RegisterNavigationProp;
}
export type LoginNavigationProp = StackNavigationProp<RootStackParamList, 'Login'>;
export interface LoginProps {
    navigation: LoginNavigationProp;
}
export type GameNavigationProp = StackNavigationProp<RootStackParamList, 'Game'>;
export interface GameProps {
    navigation: GameNavigationProp;
    route: {
        params: {
            roomId: string | null;
        }
    }
}

I don’t understand why this one raises an error while the 3 previous ones did not…

Full error :

Sorry for the long post, I can show more code if necessary but i have to admit i am truely clueless this time…
Thanks!
