QMessage box in console app slot

[qAlexKo]

Hi, Qts!

I make a console app with gui turned on (in project)

In the main function I do like this, and I then I start getting MQTT messages to receive_COMMAND_slot:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

...
auto COMMAND_subscription = _mqtt_command_client->subscribe(COMMAND_topic, (int)QOS1);
QObject::connect(COMMAND_subscription, &QMqttSubscription::messageReceived, &a, &receive_COMMAND_slot);

....
  return a.exec();
}


//here is the slot
void receive_COMMAND_slot(const QMqttMessage &msg)
{
QMessageBox::information(nullptr, "Message", "tst", QMessageBox::Yes, QMessageBox::No );
}
code_text

When I've got a message in receive_COMMAND_slot I see a message box "tst".
But after pressing OK, the app closes without warnings. The problem is in the way
I process the QMessageBox - if I don't use it -- the app is continie its working OK. Can you suggect to me why I can't use a QMessage box in my receive_COMMAND_slot slot?
