I'm developing a NEXT JS project and can't find a solution for a twice rendering app!

Problem

After adding rewrites to next.config.js, App is rendered twice. If remove, rendred once.

next.config.js

async rewrites() {
  return [
    {
      source: '/about',
      destination: '/',
    },
  ]
},

_app.js

function MyApp() {
  console.log('App render');

  return (<></>);
}

export default MyApp
