Error with BrowserRouter in ReactJS: react.development.js:209 Warning: Invalid hook call. Hooks can only be called

I set up my react app like this so far:

index.js:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import {BrowserRouter, Routes, Route} from 'react-router-dom';


const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
    <BrowserRouter>
        <Route path="/" exact component={App} />
    </BrowserRouter>
);

App.js:

import './App.css';
import {useState, useEffect} from 'react';

function App() {
  const [drinks, setDrinks] = useState([]);

  const fetchData = async () => {
    const response = await fetch('https://www.thecocktaildb.com/api/json/v1/1/list.php?c=list');
    const jsondata = await response.json();
    console.log(jsondata.drinks);
    setDrinks(jsondata.drinks);
  }

  useEffect(() => {
    fetchData();
  }, [])

  return (
    <div className="App">
    <ul>
     {drinks.map((item, index) => {
      return <li key={index}><a href="">{item.strCategory}</a></li>
     })}
    </ul>
    </div>
  );
}

export default App;

But I'm getting this error in the console:

react.development.js:209 Warning: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

I'm not sure why
