Katalon can't identify elements in WPF app on Windows

Hi guys,
I’m testing a WPF app on Windows that Katalon can’t identify most of the elements in the app.
Katalon can only detect the elements in the pop-up windows that open through the app.

I would appreciate your help.

@gotira1659,

The unidentified elements if they are native WPF element, you can find by switching to desktop then find them under another window.

I too facing similar issue. Only the window object is detected. The controls residing on the window such as TextBox, Button are not detected. The reply from @duyluong didn’t help.
