after 2.1.4 Homebridge doesn't start
### What happened?

Hey Community,
after Update, my homebridge get stuck in a start loop with this message:

Dec 25 12:15:29 raspberrypi systemd[1]: homebridge.service: Main process exited, code=killed, status=11/SEGV
Dec 25 12:15:29 raspberrypi systemd[1]: homebridge.service: Failed with result 'signal'.
Dec 25 12:15:30 raspberrypi systemd[1]: Stopped Node.js HomeKit Server.

After downgrade to 2.1.3 my Homebridge works fine.
Only the Eufy Plugin with 2.1.3 dont work. 

Thanks and merry christmas
Martin
