Reproducible client crash when Bluetooth headsets connect/disconnect with PC

[fearian]

Description:
When a Bluetooth headset is disconnected from a Windows PC, this can cause the game client to silently crash. In some cases, an error message appears.

This is notable due to the current long queue times, where a headset might not be able to remain connected for the length of the queue, or is disconnected as some part of a sleep function on the headset.

Frequency:
100% of the time

Repo Steps:
1. Pair a Bluetooth headset with Windows, being able to establish a connection with the device.
2. Log in through the launcher, and start the game client.
3. Turn on the Bluetooth headset, and connect with Windows.
4. Turn off the Bluetooth headset so that the audio device is disconnected.
5. Turn on the Bluetooth headset again, reconnecting the audio device.

If this does not reproduce the crash, try the following:
3a. Click on the Windows sound icon in the system tray, and change the audio output device from: "Headphones (Your Headset Name)" to "Headphones (Your Headset Name Hands-Free AG Audio)" or vice versa


Tested confirmed with:
- Bose NC 700 Headphones
- Anker SoundCore Spirit X

(A bluetooth headset is connected to a windows PC.
The output device is switched beetween Audio and Headset modes.
The bluetooth headset is turned off, disconnecting the device.
When the headset it turned on again, it automatically reconnects, and the FFXIV client crashes without warning.)
