What version of Roon are you using on the Core, Build 1223? There have been reports of Roon being unstable on some MacOS Ventura systems occurring since November:
While extremely annoying, it is not consistent across all installations (e.g… I have Ventura on a 2019 MBPro without and don’t have any issues with Roon 2.0). One recommendation would be to monitor these threads and the updates for any resolution and maintain Monterey for the timebeing.
