How to get rid of automatic authorization after registration in Laravel 5.4?

Question

Laravel

When using Laravel basic authorization/registration, which is generated by artisan, there was a problem: after successful registration, the user is automatically authorized on the site. According to my idea - the user receives login data by mail and does not specify a password during registration. Accordingly, authorization is out of place.
I was looking for solutions to this problem, the most popular of them is to override the register method in RegisterController.php, taking it from the source file:

public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

        $this->guard()->login($user);

        return $this->registered($request, $user)
                        ?: redirect($this->redirectPath());
    }

and delete the line there:
$this->guard()->login($user);
Sounds logical, and I got to that myself. But for some reason, the solution does not help, and when registering a user, it still authorizes. The rest of the solutions found also failed.
Now the controller code completely looks like this (I lost the comments, otherwise it turns out bold):

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Mail\RegistrationSuccess;
use Illuminate\Support\Facades\Mail;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Http\Request;
use Illuminate\Auth\Events\Registered;

class RegisterController extends Controller
{

    use RegistersUsers;

    protected $redirectTo = '/cp';

    public function showRegistrationForm()
    {
        return view('auth.register', ['no_padding' => true]);
    }

    public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

        return $this->registered($request, $user)
                        ?: redirect($this->redirectPath());
    }

    public function __construct()
    {
        $this->middleware('guest');
    }

    protected function registered(Request $request, $user)
    {
        return view('info', [
            'breadcrumbs' => [
                                [
                                    'name' => 'Регистрация',
                                    'href' => route('register')
                                ],
                                [
                                    'name' => 'Завершение',
                                    'href' => '#',
                                    'current' => true
                                ]
            ],
            'page' => [
                'title' => 'Завершение регистрации',
                'content' => 'Регистрация успешно завершена! На адрес '.$request->email.' отправлена информация с данными для входа. Если не видите письма - проверьте его в папке "Спам". Для повторной отправки письма запросите восстановление пароля на странице авторизации'
            ]
        ]);
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'first_name' => 'required|string|max:255',
            'last_name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
        ]);
    }

    protected function create(array $data)
    {
        $password = str_random(16);

        $user_data = [
            'first_name' => $data['first_name'],
            'last_name' => $data['last_name'],
            'email' => $data['email'],
            'generate_pass' => $password,
            'password' => bcrypt($password),
        ];

        $create_user = User::create($user_data);
        if($create_user){
            Mail::to($create_user)->send(new RegistrationSuccess($user_data));
            unset($user_data);
        }
        else{
            dd('error');
        }
    }

}

Who can faced similar? Thanks in advance.

In fact, in the default version of laravel authorization, it is enough to comment out the line in the RegistersUsers trait. $this->guard()->login($user);
There is an idea that the authorization was somehow changed, which is why such a problem arises.
I would advise you to install xdebug and follow step by step how the registration is going on (which will save time on finding a solution, and it will become clearer how it works "inside")
As an option that needs to be considered last - kill the session manually after registration
