Why does the Stand-Alone React Native Debugger show an undefined redux state?

Question

I’m using the stand-alone React Native Debugger. It connects, but shows the redux state as undefined. I already tried all versions I found by browsing the internet. This approach is the one that shows better results but has this little problem

The value called "Your Wallet" is the variable totalWallet, that's getting its value from the redux state.

It is working, but the debugger doesn't show this state

I’m declaring the provider as

const App = () => {
    return (
        <Provider store={myStore}>
            <NavigationContainer>
                <Stack.Navigator
                    screenOptions={{
                        headerShown: false
                    }}
                    initialRouteName={'MainLayout'}
                >
                    <Stack.Screen name="MainLayout" component={Tabs} />
                </Stack.Navigator>
            </NavigationContainer>
        </Provider>
    );
};

Where myStore is:

import { createStore, applyMiddleware, compose } from 'redux';
import { Provider } from 'react-redux';
import thunk from 'redux-thunk';

import rootReducer from './stores/rootReducer';

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const myStore = createStore(rootReducer, /* preloadedState, */ composeEnhancers(thunk));

and rootReducer is

import { combineReducers } from 'redux';

import tabReducer from './tab/tabReducer';
import marketReducer from './market/marketReducer';
import logReducer from './log/logReducer';

export default rootReducer = combineReducers({
    tabReducer,
    marketReducer,
    logReducer
});

What could I be missing?

Thanks in advance
