I have a problem with student registers, where it doesn't work and stays there

RegisterController.php

class RegisterController extends Controller
{
    use RegistersUsers;

    protected $redirectTo = RouteServiceProvider::HOME;

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


    protected function validator(array $data)
    {
        return Validator::make($data, [
            'nis' => ['required'],
            'nama_siswa' => ['required', 'string', 'min:3', 'max:50', 'unique:siswas'],
            'tempat_lahir' => ['required'],
            'tanggal_lahir' => ['required'],
            'jenkel' => ['required'],
            'alamat' => ['required'],
            'no_telp' => ['required', 'int', 'min:12', 'max:12', 'unique:siswas'],
            'email' => ['required', 'string', 'email', 'min:3', 'max:50', 'unique:siswas'],
            'password' => ['required', 'string', 'min:5'],
            'kelas_id' => ['required'],
            'walas_id' => ['required'],
            ]);
    }

    protected function create(array $data)
    {
        return Siswa::create([
            'nis' => $data['nis'],
            'nama_siswa' => $data['nama_siswa'],
            'tempat_lahir' => $data['tempat_lahir'],
            'tanggal_lahir' => $data['tanggal_lahir'],
            'jenkel' => $data['jenkel'],
            'alamat' => $data['alamat'],
            'no_telp' => $data['no_telp'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'kelas_id' => $data['kelas_id'],
