Bricasti DAC no longer showing up in audio devices

I have tried every reading all that I thought to be relevant to my problem, My Bricasti DAC and Mac mini worked flawlessly until the auto update. Now My Dac no longer shows up on audio devices as a selection. All operating systems are current and up to date.

This may sound stupid, but could you restart Roon or RoonServer, whichever you’re using and also power cycle the DAC?
