Greetings Adventurer and thank you for posting in the Final Fantasy XIV Technical Support Forums!

I'm very sorry to hear about this ongoing issue regarding the controller not properly allowing Final Fantasy XIV to launch and causing it to crash. I'd like to get some more information regarding your issue. Could you please provide us with the following:

- What platform are you trying to run the game with a controller on (PC (Windows) or Steam):
- What is the make and model of the controller you're having issues with:
- Is the controller fully synced via Bluetooth or wired cable to the system:
- As you've tried some troubleshooting already, have you found success in playing Final Fantasy XIV with any other controller aside from the one currently causing the crashing? (Only if applicable):

While we await your response, I would advise to try a clean reinstall (Uninstall any and re-download/install up to the most recent) of any drivers for the controller.
