я сделал небольшие изменения в моем файле models.py, тогда он работает.

@receiver(post_save, sender=User)
def update_user_profile(sender, instance, created, **kwargs):
    """
    Signals the Profile about User creation.
    """
    if created:
        Profile.objects.create(user=instance)
    instance.profile.save()
