I cannot change one email type

If i choose email type customer_processing_order, then I get 500 Error from backend.

Error: [01-Oct-2019 08:47:49 UTC] PHP Fatal error: Uncaught Error: Call to a member function needs_payment() on bool in /wp-content/plugins/woocommerce-germanized/includes/class-wc-gzd-checkout.php:309

The funktion, where it happens is:

public function add_payment_link( $order_id ) {
$enabled = true;
if ( get_option( 'woocommerce_gzd_order_pay_now_button' ) === 'no' ) {
	$enabled = false;
}
$order = wc_get_order( $order_id );
if ( ! $order->needs_payment() ) {
	$enabled = false;
}
$disabled_methods = get_option( 'woocommerce_gzd_order_pay_now_button_disabled_methods', array() );
...

The problem is in Woocommerce Germanized, but a lot of people use it too ??

Can you help with it?
