How do I get this Registration Page to work?

class Register extends FilamentRegister
{
    public function form(Form $form): Form
    {
        return $form
            ->schema([
                $this->getNameFormComponent(),
                $this->getEmailFormComponent(),
                $this->getPasswordFormComponent(),
                $this->getPasswordConfirmationFormComponent(),
            ])
            ->statePath('data')
            ->model(User::class);
    }

    public function register(): ?RegistrationResponse
    {
        parent::register();

        $user = $this->createUser();

        event(new Registered($user));

        Filament::auth()->login($user);

        session()->regenerate();

        return app(RegistrationResponse::class);
    }

    public function createUser(): User
    {
        $data = $this->form->getState();

        return DB::transaction(function () use ($data) {
            return tap(User::create($data), function (User $user) {
                $this->createCompany($user);
            });
        });
    }

    protected function createCompany(User $user): void
    {
        $user->ownedCompanies()->save(Company::forceCreate([
            'user_id' => $user->id,
            'name' => explode(' ', $user->name, 2)[0]."'s Company",
            'personal_company' => true,
        ]));
    }
}
