May try this:

- Disable the Xbox overlay, it seems to cause crashes while using a PS4 controller on PC.

- Disable the Discord overlay, just in case.

- Deinstall ICUE4 from Corsair if you´ve it. I know that it can cause rare crashes or Audio-issues. Never had an issue with Razor so far.

- Set your FF14 audio settings to the used device, NOT on Default. (Go under Sound-settings, scroll down to Advanced Soundsettings, select your Realtek Device at FF14 tab.)

- If you play with Controller deactivate it in the Sound-device Tab in your Device-manager.
