尝试在单击名称后将我的设置屏幕链接到登录/注册屏幕，为什么我一直收到“未定义不是函数”？

Question

我想做一个简单的任务，就是从一个屏幕转到另一个屏幕，但无论我做什么都行不通。我已经安装了 react-navigation/stack 和 react-navigation/native-stack，但都无法使用我所拥有的，是因为 Tabs 吗？

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import Tabs from './navigation/tabs';
import "react-native-url-polyfill/auto"
import LogInSignUp from './SettingsScreen/LogInSignUp';


const Stack = createStackNavigator();

const App = () => {
    return (
        <NavigationContainer>
          <Stack.Navigator screenOptions={{ headerShown: false }}>
            <Stack.Screen name="Home" options={{title: "Welcome"}} component={Tabs} />
            <Stack.Screen name="Settings" component={Tabs} />
            <Stack.Screen name = "LogInSignUp" component={LogInSignUp}/>
          </Stack.Navigator>
    </NavigationContainer>
  );
};

export default App;

import { Text, StyleSheet, View, Button, } from "react-native";
import { StatusBar } from "expo-status-bar";


const Settings = (navigation) => {
    return (
      <View style = {styles.container}>
        <Button title = "LogIn/SignUp" onPress={() => navigation.navigate("LogInSignUp")}></Button>
      </View>
      
    );
  }

  const styles = StyleSheet.create({
    container: {
      flex: 1,
      alignItems: 'center',
      justifyContent: 'center',
    },
    
  })

export default Settings

import React from 'react'
import { StackActions } from '@react-navigation/native';

const LogInSignUp = (navigation) => {
  return (
    <div>LogInSignUp</div>
  )
}

export default LogInSignUp

我试图找到解释问题的教程，他们的所有代码看起来都像我的，只是将名称切换到我的 .js 文件，但没有任何效果。
