Why render error in react v18 occures although I do not use legacy code?

Question

Hy, guys! I have a render error in my react v18 code like this:

Warning: react-dom.development.js:86 Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot

I don't use legacy ReactDom.Render() but error occures anyway. Here is my code:

import React from 'react';
import {createRoot} from 'react-dom/client';
import {BrowserRouter,Routes,Route} from 'react-router-dom';
import {Layout} from './layout';
import {Home} from './home';
import {About} from './about';
import {Contacts} from './contacts';
import {NoMatch} from './noMatch';

const root=createRoot(document.querySelector('#root'));
root.render(
    <BrowserRouter>        
        <Routes>
            <Route path='/' element={<Layout/>}>
                <Route index element={<Home/>}/>
                <Route path='about' element={<About/>}/>
                <Route path='contacts' element={<Contacts/>}/>
                <Route path='*' element={<NoMatch/>}/>
            </Route>
        </Routes>
    </BrowserRouter>
)

and my json file:
