Can't restart after installing Dwains Dashboard

[remirr]

I have installed the latest version of Dwains Dashboard but now I can no longer restart HA. When I try to add the integration I get an error saying: Config flow could not be loaded: {"message":"Invalid handler specified"}

When I try to restart I get

Downgraded to 3.6.0, that worked. Then upgraded to 3.7.1 and it stopped working again.
