React Native：底部标签按下不起作用

Question

in my react-native app I have a bottom tabs navigation, I added a tabPress listener to one of the screens but for some reason now all screens don't work, I can't navigate to a different screen when I tap the icons...

The objective was to lock a screen depending of the day but now ALL screens are locked for some reason and I can't navigate to ANY screen!

<Tab.Navigator /* options here... */>
        <Tab.Screen name="Descubre" component={STACK1} />
        <Tab.Screen name="Favoritos" component={STACK2} 
        listeners={{
          tabPress: (e) => {
              if(root.mapStore.isoWeekDay == 6)
              {
                e.preventDefault();
              }
          },
        }}
        />
        <Tab.Screen name="Pedidos" component={STACK3} />
        <Tab.Screen name="Más" component={STACK4}/>
    </Tab.Navigator>

I'm guessing this is the default behaviour stablished by React Native for this event, check section Listening to events

If you want only to block one of the screens in this point, you could do the following:

<Tab.Navigator>
<Tab.Screen name="Screen 1" />
<Tab.Screen name="Screen 2"
    options={{
        tabBarButton: disabled ? DisabledTabBarButton : EnabledTabBarButton,
    }}
/>
</Tab.Navigator>

Where DisabledTabBarButton is:

const DisabledTabBarButton = ({ style, ...props }: BottomTabBarButtonProps) => (
    <Pressable disabled style={[{ opacity: 0.2 }, style]} {...props} />
)

And enabled one:

const EnabledTabBarButton = ({ style, ...props }: BottomTabBarButtonProps) => (
    <Pressable style={[{ opacity: 1 }, style]} {...props} />
)

Also, you could do the following while creating your tab navigator:

const TabNavigator = createBottomTabNavigator({
First:{
    screen: First,
},
Second:{
    screen: Second,
},
Third:{
    screen: Third,
}
}, defaultNavigationOptions: ({ navigation }) => ({
  tabBarOnPress: ({ navigation, defaultHandler }) => {
    if (
      navigation.state.routeName === "Route disabled"
    ) {
      return null;
    }
    defaultHandler();
  },})
