I've installed the Unity Hub but for reason it starts really slow. It takes about 1+ minute before it even starts and at first I thought this was for checking my system for unity installations, but this behavior is always. Another issue is that when the hub is finally started, it asks me with 2 buttons to login my existing account or create a Unity ID. (Btw, doesn't this need to be 'an' instead 'a'?) But when I click the button 'log into my existing account' a popup appears without any GUI or content and stays that forever. In this case the hub is completely unusable for me. My machine runs Windows 10 insider preview build 17063 (most up to date when writing this).
