Description Of Issue
My set-up of Core server + CXN v2 + iPhone/iPad is working perfectly. I’m trying to add a laptop connected via 3.5mm audio jack to amp+speakers running Roon Bridge but it is crashing consistently at start-up. I see the musical quote splash screen then nothing else. Windows event logs report the following errors:

Hi @Calum_Loudon,

Would you kindly use the directions found here and send us over a set of logs using a shared Dropbox link? Thanks!

Sorry, forgot to do that: link is

Hi @Calum_Loudon,

Just to confirm, Roon Bridge is installed and not the version of Roon with UI, correct? It looks like it’s trying to call UI components here which are not a part of Roon Bridge.

Well, that’s odd/embarrassing. I was 99% sure I had installed the bridge not the server (and done so a couple of times), but just uninstalled everything and reinstalled from this link and no longer see it crashing: there’s no splash screen and the RoonBridge exe keeps running. The core isn’t reporting any new audio devices, mind, but that’s a different problem I can investigate - please feel free to close this one.
