How to display users associated with a node through Views
It seems to me that since your node reference field is on your user object and you want to list users, all you have to do is:


create a view listing Users
add a contextual filter corresponding to your entity reference field. The entity reference field on the User should appear in the contextual filters list. Choose that one.
Choose where the contextual filter value is coming from. If your view will be at myview/nid, where nid is the node id you want to use to filter, then you don't need to choose any other behavior. If you'll be displaying this view on a node page, use the default->content id from URL option.
Choose your user name fields without relationships. There is no relationship needed unless you need to bring in fields from the node being referenced.
