You cannot serialize or unserialize PDO instances

Good Morning,

I've been trying to get a login for some time now.
First one dan wanted the other one not now I unfortunately get a “You cannot serialize or unserialize PDO instances” error.

In this regard, I've already looked at the old post https://forum.nette.org/…do-instances me, but unfortunately without success, unfortunately, the post is already 3 years old.

Now I hope you can help me here.

Application info:

<?php

namespace App\Presenters;

use Nette;
use Nette\Application\UI\Form;
use Nette\Database\Connection;
use App\Forms\SignFormFactory;
use Nette\Security\Passwords;

class SignPresenter extends Nette\Application\UI\Presenter
{

    /** @var Nette\Database\Context */
    private $database;

    /** @var User */
    public $user;

    public function __construct(Nette\Database\Context $database)
    {
        $this->database = $database;
    }

    protected function createComponentSignInForm()
    {
        $form = new Form;
        $form->addText('username', 'Username:')
            ->setRequired('Please enter your username.');

        $form->addPassword('password', 'Password:')
            ->setRequired('Please enter your password.');

        $form->addSubmit('send', 'Login');

        $form->onSuccess[] = [$this, 'signInFormSucceeded'];
        return $form;
    }

        $userDB = $this->database->table('d-user')->where('Nick', $values->username)->fetch();
        $passwordDB = Passwords::verify($values->password, $userDB['Passwort']);

        $firmaStatus = $this->database->table('d-firma')->where('ID', $userDB['D-Firma_ID'])->fetch();
        if(!$userDB != !$passwordDB){
            $this->flashMessage('Benutzer und/oder Passwort falsch.');
        }elseif(!$firmaStatus['Active']){
            $this->flashMessage('Ihr Unternehmen ist nicht berechtigt diese Anwendung zu nutzen.');
        }elseif(!$userDB['Active']){

            //$this->redirect('MainHomepage:');
        }
    }

}

		} catch (Nette\Database\UniqueConstraintViolationException $e) {

	}
}



class DuplicateNameException extends \Exception
{
}

This is my motto I fall back on:

CREATE TABLE `d-user` (
  `ID` int(11) NOT NULL,
  `R-V.name` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
  `R-V2.name` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
  `R-N.name` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
  `Grade` enum('Chef','Schicht-Leiter','Normal','Admin') COLLATE utf8_unicode_ci DEFAULT 'Normal',
  `Nick` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
  `Passwort` varchar(150) COLLATE utf8_unicode_ci DEFAULT NULL,
  `Active` tinyint(1) DEFAULT '1',
  `Status` enum('Intern','Extern') COLLATE utf8_unicode_ci DEFAULT NULL,
  `Mail` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,
  `D-Firma_ID` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Now I always get the above error …

This is currently happening via XAMPP Local
