Thanks for letting us know that the issue re-occurred after you downloaded a macOS beta - which beta version was downloaded?
Since beta testing means that it hasn’t yet been released to the public, there may be some incompatibility issues or other concerns that pop up, so until it’s released to the public, it won’t be fully supported in Roon. You can read more about our explanation about this here: macOS Beta and Roon
Can you please full reboot all devices within your Setup (Core, router, remotes, etc.). You’ll want to power them down, unplug them for a few minutes, plug them back in and power them back on, does the same issue still occur?
If so, can you please play to “System Output” and let us know if it continues?
Thanks so much!
