Unhandled Runtime Error

[xingsheng-lim]

I'm using nextjs 15 and react 19, and it keeps giving this error, which I can't fix My code:

"use client";

import * as Media from "@react-av/core"; import { useEffect, useState } from "react";

export default function Demo() { const [mounted, setMounted] = useState(false);

useEffect(() => { setMounted(true); }, []);

if (!mounted) return

Loading...

;

return (

); }

In fact, I feel that it is not a problem with this lib, but a compatibility issue caused by the recoil lib used in the lib, especially when using react 19 or turbo.
