[solved] Error: Element type is invalid: expected a string (for built-in components)

Hello Everyone,
I am facing this error in my Reactjs App when I try to install react-snap updated the index.js this error came suddenly 

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object.

The used code in index.js is 

import 'react-app-polyfill/ie11';
import 'react-app-polyfill/stable';
import 'react-perfect-scrollbar/dist/css/styles.css';
import 'react-draft-wysiwyg/dist/react-draft-wysiwyg.css';
import 'react-quill/dist/quill.snow.css';
import 'prismjs/prism';
import 'prismjs/components/prism-bash';
import 'prismjs/components/prism-javascript';
import 'prismjs/components/prism-jsx';
import 'nprogress/nprogress.css';
import 'src/__mocks__';
import 'src/assets/css/prism.css';
import 'src/mixins/chartjs';
import React from 'react';
import { hydrate, render } from "react-dom";
// import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { enableES5 } from 'immer';
import * as serviceWorker from 'src/serviceWorker';
import store from 'src/store';
import { SettingsProvider } from 'src/contexts/SettingsContext';
import App from 'src/App';

enableES5();

const APP = ( 
<Provider store={store}>
 <SettingsProvider>
 <App />
 </SettingsProvider>
</Provider>
);

const rootElement = document.getElementById("root");
if (rootElement.hasChildNodes()) {
 hydrate(<APP />, rootElement);
} else {
 render(<APP />, rootElement);
}

serviceWorker.register();

What should I do?
