Thank you for reaching out Beauclair! I am deeply sorry you have experienced such a hard time with the Crusader Kings 3 trainer.
Unfortunately, there is no way for you to add the trainer to the queue but what I STRONGLY suggest is reaching out to the trainer discussion page listed here → Crusader Kings III Cheats and Trainer for Steam
