Cannot open Settings -> Home Assistant Cloud -> Alexa: Manage Entities with this integration enabled

When this integration is enabled opening the above mentioned page results in the 3/4 circle continuing to show. With this integration disabled the page opens instantly.

The Home Assistand Core log file contains this error:

Don't see this happening. Can only think if you have got a room that you have deleted that is exposed to Alexa? If so, delete the device with the integration enabled. Let me know.

EDIT: Just looking at the code, do you have an heating actuator with floor temp sensor?

OK, managed to recreate and fix the issue. v3.3.2 just released with this fix in. Please can you test and confirm.

Looks like this has fixed it. Thanks!
