HomeKit shows removed Apple TV as cannot connect to home hub.

Last year, I removed an Apple TV from my accounts, and it still displays in HomeKit as “Cannot connect to Home Hub.” Despite numerous attempts to resolve this issue, I have been unable to find a solution. Furthermore, the HOME HUB has now become 3 unresponsive home hubs. . The AppleTV does not show in any room in my HomeKit setup. It’s just unresponsive.
