Error: (0 , _context_UserContext__WEBPACK_IMPORTED_MODULE_3__.useUser) is not a function

I am trying to pass props from Dashboard to Header (Header in in the Layout), It works in dashboard, I can import it and get setUsers by destructuring assingment, but in Header, I cant do this for some reason
Layout.tsx:

import { UserProvider } from "@/context/UserContext";
import type { Metadata } from "next";
import { Montserrat } from "next/font/google";
import '../globals.css'
import Header from "./header/Header";
const monoton = Montserrat({subsets: ['latin']});

export const metadata: Metadata = {
  title: "Home",
  description: "Shared Drive project",
};


export default function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <UserProvider>
      <html lang="en" data-theme="light">
        <body className={monoton.className}>
          <Header />
          <main>
            {children}
          </main>
        </body>
      </html>
    </UserProvider>

  );
}

Dashboard.tsx:

'use client'
import React, { useEffect, useState } from 'react';
import { useUser } from '@/context/UserContext';

const Dashboard = () => {
  const { setUser } = useUser();
  useEffect(() => {
    const fetchUserData = async () => {
      console.log('dada')
      const response = await fetch('http://localhost:2525/api/user', { credentials: 'include' });
      if (response.ok) {
        const data = await response.json();
        setUser(data);
      }
    };
    fetchUserData();
  }, []);
  return (
    <div>
      Dashboard
    </div>
  );
};

export default Dashboard;

UserContext.tsx:

'use client'
import React, { createContext, useContext, useState, ReactNode } from 'react';

export type UserType = { 
  name: string; 
  id: string; 
  role: string; 
  email: string; 
  password: string;
};

export type UserContextType = {
  user: UserType | null;
  setUser: React.Dispatch<React.SetStateAction<UserType | null>>;
};

const UserContext = createContext<UserContextType>({
  user: null,
  setUser: (user) => {user= user},
});

export const useUser = () => useContext(UserContext);

export const UserProvider = ({ children }: { children: ReactNode }) => {
  const [user, setUser] = useState<UserType | null>(null);

  return (
    <UserContext.Provider value={{ user, setUser }}>
      {children}
    </UserContext.Provider>
  );
};
