Why can’t i access the protected routes even after the authentication, in clerk

enter image description here

import { clerkMiddleware, createRouteMatcher } from '@clerk/nextjs/server'

const isPublicRoute = createRouteMatcher(['/sign-in(.*)', '/sign-up(.*)'])

const isProtectedRoute = createRouteMatcher(['/dashboard(.*)'])
export default clerkMiddleware((auth, req) => {
  if (!isPublicRoute(req)) {
    auth().protect()
  }

  if (isProtectedRoute(req)) auth().protect()
})

export const config = {
  matcher: [
    // Skip Next.js internals and all static files, unless found in search params
    '/((?!_next|[^?]*\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)',
    // Always run for API routes
    '/(api|trpc)(.*)',
  ],
}

this is the middleware, before sign in i cant access any page. All the pages are protected except sign in and signup pages. After sign in the URL is{ http://localhost:3000/sign-in?redirect_url=http%3A%2F%2Flocalhost%3A3000%2F }

GET /sign-in?redirect_url=http%3A%2F%2Flocalhost%3A3000%2Ftest 200 in 88ms
GET /sign-in?redirect_url=http%3A%2F%2Flocalhost%3A3000%2Ftest 200 in 41ms
GET /sign-in/SignIn_clerk_catchall_check_1723370469288 200 in 46ms

After sign in this is the error i get in the terminal. i am being redirected to the above URL after sign in.
I cant access the dashboard or any other page. I am redirected to above URL.
how to change this.

I tried reading clerk docs, i tried chat-GPT i tried stack overflow. i tried every thing i can , but nothing changed.
