I'm receiving the following error when trying to run my react app:

D:/React/my-components/src/App.tsx TypeScript error in D:/React/my-components/src/App.tsx(23,4): JSX element type 'Confirm' is not a constructor function for JSX elements. Type 'Confirm' is missing the following properties from type 'ElementClass': context, setState, forceUpdate, props, and 2 more. TS2605

21 |         </a>
22 |       </header>
23 |      <Confirm />
   |      ^
24 |     </div>
25 |   );
26 | }

Here is my Confirm component code

import * as React from "react";

class Confirm extends React.Component{
  render(){
     return (
      <div className="confirm-wrapper confirm-visible">
   <div className="confirm-container">
   <div className="confirm-title-container">
   <span>This is where our title should go</span>
   </div>
   <div className="confirm-content-container">
   <p>This is where our content should go</p>
   </div>
   <div className="confirm-buttons-container">
   <button className="confirm-cancel">Cancel</button>
   <button className="confirm-ok">Okay</button>
   </div>
   </div>
   </div>
     );
 }
 
}
export default Confirm;

And App.tsx code

import React from 'react';
import logo from './logo.svg';
import './App.css';
import Confirm from './Confirm';

const App: React.FC = () => {
  return (
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.tsx</code> and save to reload.
        </p>
        <a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
        >
          Learn React
        </a>
      </header>
   <Confirm />
    </div>
  );
}

export default App;

This is my package.json

Thank all , i have fixed this error by run following command

yarn upgrade @types/react@latest

I had a component named Component.tsx (camelcase) and a helper called component.ts (lowercase) and this seemed to make these become mixed up. I was importing them in the same file also so I just renamed the Component one.
