HELP: Next.js course 'use client' files onClick just doesn't work

Next.js
1

For some reason, NO ‘use client’ pages can get the “onClick” to work at all. The button clicks, does nothing. Tried adding a console.log(‘clicked’). Nothing. Tried changing it to a click handler, same, nothing. Any ideas? Otherwise I have to skip dynamic routing because it isn’t working @moshhamedani

'use client';
import {useRouter} from 'next/navigation'
import React from 'react';


const NewUserPage = () => {

 const router = useRouter();

  return (
 
      <button className="btn btn-primary" onClick={ () =>{
        console.log('working');
        router.push('/users');
      }}>
        Create User
      </button>

  );
};

export default NewUserPage;

Not even the homepage. Is this course seriously out of date?

'use client'
import React from 'react'

const AddToCart = () => {
  return (
    <button className='btn btn-primary' onClick={()=> console.log('Click')}>Add to cart</button>
  )
}

export default AddToCart

Ok, looked all over and found on Stack Overflow that changing to Next.js 13.4.16 fixes this issue for anyone following in my footsteps.
