Updating homebridge-config-ui-x to 4.5.2 causes homebridge-config-ui-x to stop working

**Describe Your Problem:**
UI was showing an update to the homebridge-config-ui-x plugin available. I tried installing and upon restarting, the UI failed to load. I deleted the existing docker container, updated to the latest using docker-compose pull homebridge and recreated it.

To ensure it wasn't a coincidence, I tried updating again once the new container was up and running and had the same outcome.

**Logs:** (including only the pieces which seem relevant)
