Sorry, I forgot about this thread, but I was reminded today when I saw the new bug. The issue that originally affected me was https://github.com/home-assistant/core/issues/103208. It broke Xbee users, so not everyone. My Zigbee integrations didn't work after the update so I had to roll back to a backup for my first time with HA. A patch was developed, but it didn't get integrated into any of the 2023.11.x releases, which I found kind of frustrating but I figured I'd wait it out and eventually there would be a version that works again.

Fortunately I held off on 2023.12, because according to https://github.com/home-assistant/core/issues/105344 a bunch of people are having problems with this release too.
