I want to link pages using React Reuters but As far as I know everything is fine but none of the components are working properly

َApp.js

import React from "react";
import MatherComponent from "./components/MatherComponent";
import AboutMe from "./components/AboutMe";
import NoPage from "./components/NoPage";
import Layout from "./components/Layout";
import { BrowserRouter, Route , Routes } from "react-router-dom";


function App() {
    return (
        <>
            <BrowserRouter>
                <Routes>
                    <Route path="/" element={<Layout />}>
                        <Route index element={<MatherComponent />} />
                        <Route path="about" element={<AboutMe />} />
                        <Route path="*" element={<NoPage />} />
                    </Route>
                </Routes>
            </BrowserRouter>
        </>
    );
}

export default App;

Layout

import React from "react";
import { Link } from "react-router-dom";

function Layout() {
    return (
        <>
            <header className="row" style={{ padding: "10px", backgroundColor: '#ffc107', display: 'flex', marginLeft: "0px", marginRight: "0px" }}>
                <div style={{ display: 'flex' }} className="col col-4">
                    <img src="https://img.icons8.com/doodle/48/000000/apple-weather.png" alt="" />
                    <div style={{ marginRight: "10px", paddingTop: "10px" }}>آب و هوای امروز</div>
                </div>
                <div className="col col-4">
                    <button style={{ float: "left" }} className="btn">
                        <img alt="" src="https://img.icons8.com/external-those-icons-lineal-color-those-icons/48/000000/external-thermometer-weather-those-icons-lineal-color-those-icons.png" />
                    </button>
                </div>
                <div className="col col-4">
                    <Link to="/about">About Me</Link>
                </div>
            </header>
        </>
    );
}

export default Layout;

That is, it only shows the layout and does not show the other components
