Is something wrong with this module?

It says:
“Click Run to test out your code. The world waves hello back!”

But there is no output displayed. Even though it passed and the next button is active.

The same thing happened to me. For mine I dont think it should have accepted my input, MyComponent was not in the right format. <MyComponent /> is the proper way to do it. When I changed it then it rendered to the screen.

import React from 'react';
import ReactDOM from 'react-dom/client';

import MyComponent from './App';
ReactDOM.createRoot(document.getElementById('app')).render(<MyComponent />);
