WinAppDriver errors out after initial login screen

[abrody18]

System Details: WinAppDriver: 1.2.1 Katalon Studio Enterprise: 8.6.8

Summary: WinAppDriver launches ADMS (GE Digital Software) and is able to identify and connect to the initial login screen. I am able to automate logging into the app with a username and password and selecting the login button. This issue occurs after successfully logging in and winAppDriver is not able to select/locate the subsequent screen(s) and the following error is reported:

After you login is it a separate window. In case it is then you need to create a root session. And then create a session with the opened window.

[abrody18]

The initial login window pops up, I enter credentials, the login window then closes/disappears. Then a splash screen/window then appears on screen, after loading then disappears and then the application is displayed.

There is a bar at the top of the screen which is hidden until the mouse moves to the top of the screen and the various functions appear in their own window.

The best way to describe the function windows behaviour using an example is how excel used to function where you could open multiple workbooks each its own window but where still contained with the excel application itself.

Within Katalon there is a method to switch to the root, but I am not sure how to then create another session within the opened window(s)
