Module not found: Error: Package path ./client is not exported from package

It seems next-auth/client was renamed to next-auth/react in v4:

https://github.com/nextauthjs/next-auth/releases/tag/v4.0.0-beta.1

Along with next-auth/react, Provide was renamed to SessionProvider. It should be as follows,

import { SessionProvider } from "next-auth/react"

export default function App({
  Component,
  pageProps: { session, ...pageProps },
}) {
  return (
    <SessionProvider session={session} refetchInterval={5 * 60}>
      <Component {...pageProps} />
    </SessionProvider>
  )
}

i think you should use "next-auth": "^3.29.0", this version of next-auth
