[Escalated to 2nd Tier] Integration with crm order language is missing

Background of the issue:
Hi! I had a problem on site https://wpml.org/forums/topic/instructions-to-payment-method-sent-in-incorrect-language/, this ticket was marked as resolved, but I have found the bug. I'm using wpml + woocommerce and custom integration with crm. It sends order on order creation
add_action( 'woocommerce_checkout_update_order_meta', function ( $order_id ) {
do_action( 'onebox_send_order', $order_id );
}, 9999 );
add_action( 'onebox_send_order', [ $this, 'send_order' ] );

public function send_order(
int $order_id, array $args = [
'customfields' => []
]
): void {
//handle data
$response = $this->send_request( 'order/set/', [ $order_data ], $order );

if ( isset( $response['dataArray'] ) ) {
$order->update_meta_data( 'onebox_id', $response['dataArray'][0] );
$order->save();
}
}

When the $order->save() is done, the language data dissapears. If I comment this row it works. As I understand, WPML somehow interfere when the order is saved by woocommerce. What is the correct way to fix the problem, so wpml language won't be erased. By missing language I mean that wpml_language meta is missing or has default language instead of secondary language. I'm using HPOS so it will be a problem to replace $order->save() with just update_post_meta
