I am getting this error after I npm install and import MonacoEditor into my react functional component.

This is some of my code:
I have version 3.5.8 installed.

`import React, { useState, useContext } from "react";
import MonacoEditor from "@uiw/react-monacoeditor";

<MonacoEditor
value={code}
language={language}
onBlur={handleCodeChange}
onChange={handleCodeType}
options={{
theme: "vs-dark",
}}
/>
`
No matter what options I pass in, as long as MonacoEditor is there, I get this error:

Cannot read properties of null (reading 'useState')
