Integration fails to start up on HA restart (Public API)

[araines]

Recently when I've been restarting home assistant, I've been left with failures for the LW integration to start up.

HACS LW Plugin Version: v3.5.15 HACS Version: 1.26.2 Home Assistant Version: 2022.7.5

The way I've been able to get things going again is by turning off the Public API, restarting to get things going. Then waiting a little while until I hit a problem where my energy monitor no longer reports updates to HA (I should raise a separate issue about that I guess!) then switch to the Public API. I think that has been the process anyway, I've been doing a lot of option/restart twiddling recently, so will be paying more attention now to give a more accurate bug report.
