Studio error on clicking "Screen" button of extended User entity

Hi,

I am trying to extend the system User entity and relevant screens.
I extended the entity, creating ExtUser. I also created a new screen extending user-edit.xml.
Now when I click the “Screen” button at the top of the entity designer, I get the following error in IDE.
