[Bug]Double instance in react

I got a render error regarding dom/client in React. I am using the react-editor-js library. I fix the issue temporarily using the ReactDom render as follows

### Problematic Index.js
`import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(



);

`

### After the fix
`import ReactDOM from "react-dom";
import React from "react";
// import { createRoot } from "react-dom/client";

import App from "./App";

const rootElement = document.getElementById("root");
// const root = createRoot(rootElement);
ReactDOM.render(, rootElement);
`
