I got the exact same problem running Roon server on Windows. Database error. I can’t see any Audio devices either. I use a bridge but it won’t show. Tried to put the DAC directly to the comp. but no luck. I can’t use Roon now.

Yes it’s working with build 882! My old database is working and now I see all albums and audio devices again. I’m so happy, thank you and the programmers for fixing this so quickly!
