[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?
