Error initializing the InputInjector in UWP

I'm using InputInjector to simulate a mouse click on a UI element in my custom UWP control (which is included into a WPF application using XamlHost). I implemented based on this article. It works fine on my PC, but on another PC can't create the Input Injector instance. When the InputInjector.TryCreate(); is called, it throws the following exception:

System.Runtime.InteropServices.COMException (0x80010117): Call context cannot be accessed after call completed. (0x80010117)
   at System.StubHelpers.StubHelpers.GetWinRTFactoryObject(IntPtr pCPCMD)
   at Windows.UI.Input.Preview.Injection.InputInjector.TryCreate()
   at >MyMethod()<

What this exactly mean? I tried to run this function on UI and background threads as well, but both fails. What could be the issue?

Update:

The other PC's OS version is 1909 (build 18363.1316), my PC's version is newer: 2004. As I see the InputInjector was introduced in 10.0.14393.0

During the testing, we can't reproduce your problem, and it looks is the OS problem, and you could you try to update the pc OS to latest version. And test again, it works fine within my environment(the newest version).
