Hello @Thomas_Strauss,
Thank you for the timestamps. After reviewing the diagnostic data we can confirm that what you are experiencing matches a known issue with the Bluesound RAAT implementation that other users have reported here:
Roon locking up with Bluesound Nodes, causing playback errors (ref#JKC0T7)
Bluesound has acknowledged the issue and is working with our partner team to resolve it. We do not have a specific timeline to share at this point. In the meantime we would recommend reaching out to Bluesound support directly to let them know you are also affected - the more users who report this, the higher priority it will receive on their end.
