I have identified a reproduceable crash on track startup regarding the MOTO M-Series.
Whenever starting a track with my MOTU M series as the audio output device (Selected or as default) the game freezes (no crash to desktop but doesn't regain responsiveness).
This freeze occurs right after the music starts.
When switching to speakers or routing audio through a virtual audio cable the crash does not occur. Or with the device selected but audio muted.
This has been happening since the Update that released the Summer campaign but before was working fine. I only just worked out the reason.
The MOTU drivers are found here https://motu.com/en-us/download/product/408/: (https://motu.com/en-us/download/product/408)
This affects all tracks on all game modes.
Multiple clean installs (including removing all temporary files) do not fix the issue.
