Is this entities somehow related to user (UserInterface)?

yes

<?php
declare(strict_types=1);

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

/**
 * @ORM\Entity()
 * @UniqueEntity(fields="email", message="email_already_taken")
 * @ORM\HasLifecycleCallbacks
 *
 */
class Customer implements UserInterface
{
   use HasId;
   use HasCreationAndUpdateTime;


    /**
     * @ORM\ManyToOne(targetEntity=Website::class)
     * @ORM\JoinColumn(nullable=true)
     */
    private ?Website $defaultWebsite;
}

Just implement \Serializable with only necessary fields

public function serialize()
{
    return serialize([
        $this->id,
        $this->enabled,
        $this->username,
        $this->password,
    ]);
}

public function unserialize($serialized)
{
    [
        $this->id,
        $this->enabled,
        $this->username,
        $this->password,
    ] = unserialize($serialized);
}
