[Bug]: Cameras all disappeared with 2.1.0-beta.2
### What happened?

Installed 2.1.0-beta.2 along with new Eufy S40. So two devices now, the new S40 and a wired 2k doorbell. Install, etc goes fine. I add new bridge to HomeKit, but no cameras appear. For either device. Nor any sensors. With prior beta doorbell was fine and showed up. The only error I get on restart is:
