React HashRouter doesn't render anything on GitHub Pages

HashRouter doesn’t render anything on GitHub pages and the console doesn’t show any errors either. Also it renders locally only if I put a # before the app name so instead of typing: localhost:3000/chat-app I have to type localhost:3000/#/chat-app.

App.js

import SignIn from './Components/SignIn';
import SignUp from './Components/SignUp';
import Home from './Components/Home';
import UserProfile from './Components/UserProfile';
import { HashRouter, Routes, Route } from 'react-router-dom'

function App() {
  return (
    <HashRouter>
      <Routes>
        <Route path="/chat-app" exact element={<Home />} />
        <Route path="/chat-app/signIn" exact element={<SignIn />} />
        <Route path="/chat-app/signUp" exact element={<SignUp />} />
        <Route path="/chat-app/userProfile" exact element={<UserProfile />} />
      </Routes>
    </HashRouter>
  );
}

export default App;

package.json:

I have tried some fixes I found online but none of them work. If you need the repo link here it is: https://github.com/melosshabi/chat-app

I have tried changing the import from: import { HashRouter as Router, Routes, Route } from 'react-router-dom'
to: import { HashRouter, Routes, Route } from 'react-router-dom'

I have tried changing the app name.

I also tried changing :<Route path="/chat-app/home" element={<Home />} />
to: <Route path="/chat-app" exact element={<Home />} />

>Solution :

Remove "/chat-app" from all the routes since including this would make the absolute URLs https://melosshabi.github.io/chat-app/#/chat-app and https://melosshabi.github.io/chat-app/#/chat-app/signin, etc.

If necessary you can specify a basename prop on the router. I don’t think it will be required in your case.

There is also no exact prop on the Route component; in RRDv6 all routes are always exactly matched.

function App() {
  return (
    <HashRouter basename="/chat-app"> // <-- if necessary
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="/signIn" element={<SignIn />} />
        <Route path="/signUp" element={<SignUp />} />
        <Route path="/userProfile" element={<UserProfile />} />
      </Routes>
    </HashRouter>
  );
}
