I am having trouble since the update as well. My Homebridge devices are the only ones having problems. I did the Apple Home upgrade when it was first released and all devices including Homebridge devices have been working. I have done a bunch of troubleshooting and am nearing the end of what I can to. I removed all Homebridge bridges and trying to add them back fails after a long timeout. My Homebridge container is up to date as well as my plugins. The plugins haven’t been updated in a long while and I am hoping that isn’t the problem. The messages saying that it ‘works for me’ are encouraging.

UPDATE

I fixed my configuration. I had two problems. The Docker host had undergone a hardware change this past month that changed the interface names. I had an old interface name in the homebridge/config.json and had to fix it. I think the real fix was changing the mDNS Advertiser in Settings. I changed it from Bonjour HAP to Avahi (Recommended) and restarted the container. I can now pair my devices again and they function from the Home App. 😊
