laravel-8 user table seeder does not exist

I am trying to make a login from laravel 8 but at the begging I faced an error which I cannot find a solution. The UsersTablesSeeder is created but still the compiler cannot find it

   Illuminate\Contracts\Container\BindingResolutionException 

  Target class [UsersTablesSeeder] does not exist.

      ReflectionClass::__construct("UsersTablesSeeder")

the following code shows DatabaseSeeder.php

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Eloquent::unguard();
        $this->call(UsersTablesSeeder::class);
    }
}

this is my user table

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use App\User;

class UsersTablesSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        User::create([
            'name'    => 'John Smith',
            'email'    => 'john_smith@gmail.com',
            'password'   =>  Hash::make('password'),
            'remember_token' =>  str_random(10),
        ]);
    }
}
