In build for UWP C# with IL2CPP, not working Input.GetKey and Input.GetKeyDown(Up)

We have UWP project with integrated with a Unity IL2CPP built as in example https://github.com/TautvydasZilys/unity-uwp-il2cpp-with-csharp-project-example
On page with unity SwapChainPanel call:

Code (CSharp):

1. AppCallbacks appCallbacks = AppCallbacks.Instance;
2. appCallbacks.SetSwapChainPanel(GetSwapChainPanel());
3. appCallbacks.SetCoreWindowEvents(Window.Current.CoreWindow);
4. appCallbacks.InitializeD3DXAML();

Mouse interaction works fine Input.mousePosition and Input.GetMouseButton. But is user click on UWP UserControl or Button or any other UWP ui element unity Input.GetKey and Input.GetKeyDown(Up) stop working. At the same time, the Input.GetMouseButton continue to work as expected.

Can anyone tell me how to solve issue like this?

 

By the default "Input Source" have "Core Window" value. I try build with other parametr values. If selected "Swap Chain Panel" it still work incorrect like with "Core Window" value. With "Independent Input Source" Input mouse and all GetKey(Down)(Up) functions not work at all.

 

We cannot reproduce full set of bugs on test project, but issue with "Input" that stop working after click to any UWP UI Element even if Input Source set to "Independent Input Source"
