Something Changed: Adding Apple TV Disconnects Deives in Home

I have 3 Apple TV’s. All have been updated to the latest software, restarted and unplugged/plugged in. When I add any or all of them to Homekit, my connected devices immediately become unresponsive. I have deleted & reinstalled Home on my iPhone 12 (updated to current software & restarted), rebooted modem (AT&T) and reset my router (eero6). I can add a device or two that work through Home but the instant I add one of the ATV’s as a hub, they become unresponsive. I have followed all of the actions provided by Tailwind to no avail. Screenshots of connected and disconnected (No Response) are included.
