Find UI element issue

Hi,
An error message came up while I was trying to use Ctrl+Shift+E to find UI element. Please feel free to look into, Thanks!

The window was closed while maximized.

Open the window with the toolbar button (not with Ctrl+Shift+E). Restore, close. Then Ctrl+Shift+E will work again.
