Hi @Howard_Sambol,
Thanks for reaching out to us about this issue. You noted in your post that this is happening with Sequoia. We have had other users with a similar issue who successfully fixed this issue by checking macOS System Settings > Privacy & Security > Local Network, make sure Roon is allowed. If it is already enabled, toggle it off and on again. Then reboot the Mac.
Let us know if this fixes the issue for you!
