Just chiming in here - if the update triggered the issue with Roon, a common cause is the Windows Defender firewall flagging the new Roon update because it’s technically a new binary.
If you haven’t already, add RoonServer.exe and Roon.exe to the Windows Defender safelist along with the other Roon background processes. You’ll need to repeat this step in any anti-virus or third-party network security software you have installed on Windows RoonServer machines and Remotes in this setup.
