useEffect without dependencies in react component executes twice [duplicate]

Hello I have a problem with useEffect. It is without dependencies because I want to execute this only once. I'm also using react router v6. But the useEffect in Profiles.js component runs twice and I don't know how to fix it. Below it is the App component which is the parent of Profile and the Profile component which is the problem.

App.js:

function App() {
return (
    <div>
        <Navbar />
        <Routes>
            <Route
                element={<Navigate replace={true} to={"/welcome"} />}
                path="/"
            />
            <Route element={<Profiles />} path={`/profiles`} exact />
            <Route element={<LandingPage />} path={"/welcome"} />
            <Route element={<Main />} path={"/main"} />
            <Route element={<MyProfile />} path={"/myprofile"} />
        </Routes>
    </div>
);
}

export default App;

Profiles.js:

const Profiles = (props) => {
const [profiles, setProfiles] = useState([]);

useEffect(() => {
    const fetchProfiles = async () => {
        console.log("profiles");
        // const snapshot = await get(ref(database, `users/`));
        // if (snapshot.exists()) {
        //     const response = snapshot.val();
        //     for (const uid in response) {
        //         if (uid !== user.uid) {
        //             setProfiles((prevState) => {
        //                 return [response[uid], ...prevState];
        //             });
        //         }
        //     }
        // }
    };
}, []);
return (
    <div>
        <ProfileRecommendation />
    </div>
);
};

export default Profiles;
