Cron is running but not saving entity

I am trying to create a simple hook_cron to connect with an external API, return some data and update some fields in some entities. I'm creating like this to understand better how cron works, so I will upgrade it later to a queue.

The problem is that the cron is running, but even without errors the entity is not saving or updating. If I copy the code and try to execute it with a route (not using cron), it works as intended. I really don't know what is the problem with it.

I thank you for your help.

The code below:

function correios_web_service_cron()
{
    $trackingService = \Drupal::service('correios_web_service.tracking');
    $eventService = \Drupal::service('correios_web_service.event');

    $error = null;

    try {
        $order_ids = \Drupal::entityQuery('commerce_order')
            ->condition('type', 'campaign') //! Ver se terá que mudar o tipo
            ->condition('state', $eventService->getStatusByAlias('entregue')['description'], '<>')
            ->condition('state', $eventService->getStatusByAlias('avaliado')['description'], '<>')
            ->condition('state', $eventService->getStatusByAlias('cancelado')['description'], '<>')
            ->condition('field_tracking_code', NULL, '<>')
            ->execute();

        $Orders = \Drupal::entityTypeManager()->getStorage('commerce_order')->loadMultiple($order_ids);
    }
    catch (\Throwable $e) {
        $error = $e->getMessage();
    }

    if (empty($error) && !empty($Orders)) {
        foreach ($Orders as $Order) {
            $tracking_code = $Order->get('field_tracking_code')->value;

            try {
                $response = $trackingService->trackObjectFormatted($tracking_code);

                $Order->set('state', $response['description']);
                $Order->set('field_tracking_event_code', $response['event_code']);
                $Order->set('field_tracking_event_message', $response['event_message']);
                $Order->set('field_tracking_delivery_date', $response['delivery_date']);

                $Order->save();
            }
            catch (\Throwable $e) {
                \Drupal::logger('correios_web_service_cron')->error($e->getMessage());
            }
        }
    }
    
    if (!empty($error)) {
        \Drupal::logger('correios_web_service_cron')->error($error);
    }
}
