Target class [PersonTableSeeder] does not exist

Question

I am trying to run php artisan db:seed but getting this error same running this command php artisan db:seed --class=PersonTableSeeder:

Target class [PersonTableSeeder] does not exist.
database/seeders/DatabaseSeeder.php:14
          Illuminate\Database\Seeder::call("PersonTableSeeder")
    
          +24 vendor frames
          34  artisan:37
          Illuminate\Foundation\Console\Kernel::handle(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))

P.S Everybody says to run composer dump-autoload but it doesn't help me to solve this issue. I also tried these commands with no result:

    php artisan optimize
    php artisan clear:cache
    composer clearcache
    composer dump-autoload

Also I made sure that both DatabaseSeeder and PersonTableSeeder files are in the same folder

This is my code:

DatabaseSeeder.php

<?php

use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call(PersonTableSeeder::class);
    }
}

PersonTableSeeder:

<?php

use Illuminate\Database\Seeder;
use App\Person;

class PersonTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        factory(Person::class, 50)->create();
    }
}

PersonFactory:

<?php

use Faker\Generator as Faker;

$factory->define(App\Person::class, function (Faker $faker) {
    return [
        'first_name' => $faker->firstName,
        'last_name' => $faker->lastName,
        'email' => $faker->safeEmail,
        'phone' => $faker->phoneNumber,
        'city' => $faker->city,
    ];
});
