So we might have found a solution.

The solution that worked for me was to disable all other audio sources aside from my headset in the windows sound settings.
(if you're on windows 10 open sound settings > sound control panel > then just right click disable the devices in the list apart from the one you actually want sound from)

I think the error is happening because there's audio devices trying to switch during launch? (I might be way off lol)
I hope this works for you!
