Qt does not see the UWP device for running applications (Qt 5.12.0-beta2)

I have installed Qt 5.12.0-beta2 using the online installer, and Visual Studio 2017 Community. And I have Windows 10 1809.

For example, I create a basic application Qt Quick Application - Swipe without changing anything in it.

When I try to run it through the kit Desktop Qt 5.12.0 (MSVC2017 64 bit) application start button is not active (gray button with red dot).

As I understand it, this is due to the fact that qt cannot see the uwp device.
