Problems in Laravel using queue

Question

I'm having some problems that until now i couldn't resolve. When i execute php artisan queue:work i have the next error:

[2019-09-22 23:25:20][12] Processing: App\Listeners\WelcomeNewStudentListener

[2019-09-22 23:25:20][12] Failed: App\Listeners\WelcomeNewStudentListener

Below my .env file:

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:i+VBlcoP1fQodPn+ZV9os2knWv/piI4Gb/TDr0Dmq9U=

MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"

In my EventServiceProvider.php i have the next:

<?php

    namespace App\Providers;

    use App\Events\NewStudentHasRegisteredEvent;
    //use App\Listeners\WelcomeNewStudentListener;
    use App\Listeners\RegisterStudentToNewsletter;
    //use App\Listeners\NotifyAdminViaSlack;
    use Illuminate\Support\Facades\Event;
    use Illuminate\Auth\Events\Registered;
    use Illuminate\Auth\Listeners\SendEmailVerificationNotification;
    use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

    class EventServiceProvider extends ServiceProvider
    {
        /**
         * The event listener mappings for the application.
         *
         * @var array
         */
        protected $listen = [
            //agregando mi evento
            NewStudentHasRegisteredEvent::class => [
                //aqui se agrega el listener
                \App\Listeners\WelcomeNewStudentListener::class,
                RegisterStudentToNewsletter::class,
                \App\Listeners\NotifyAdminViaSlack::class,
            ],
        ];

        /**
         * Register any events for your application.
         *
         * @return void
         */
        public function boot()
        {
            parent::boot();

            //
        }
    }

And finally in my WelcomeNewStudenListener.php

<?php

namespace App\Listeners;

use App\Mail\WelcomeNewUserMail;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Support\Facades\Mail;

class WelcomeNewStudentListener implements ShouldQueue
{

//ESTE ES EL LISTENER
    /**
     * Handle the event.
     *
     * @param  object  $event
     * @return void
     */
    public function handle($event)
    {
        //
        sleep(10); //10 seconds

        Mail::to($event->datosEnviar->email)->send(new WelcomeNewUserMail());
    }
}

Additionaly i have the jobs and the failed_jobs tables on my database.

So I haven't been able to solve that problem with queue:work
