QString "not accessible" when debugging

1. Create a new Qt Widgets Application.
2. Create a QString in the main function.
3. Place a breakpoint in the main function after the QString was created.
4. Build this on Qt for UWP and run it in the debugger.
   The breakpoint will be hit but the QString will be marked "not accessible" in "Locals" view.

The "Locals" view should show the content of the QString. When building the same application on Qt for Desktop, this seems to work correctly, even when checking "Run in Terminal".
