Nextjs: react-dom.development.js?ac89:14906 Uncaught Error: Invalid hook call. Hooks can only be called inside of the body of a function component

This is my code:

<div onClick={(e) => handleClick()}>Join Us</div>

This is handleclick:

const handleClick = () => {
    console.log(Lang.getLocale())
};

And this is my function:

class Lang {
    static getLocale() {
        const { locale } = useRouter();
        return locale?.toString()
    }
}

export default Lang

But I get this error:

react-dom.development.js?ac89:14906 Uncaught Error: 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.
