CloseDevice() function causing the application to hang

[BQTHake003]

I am using a .NetFramework 4.8 Windows application where I have installed the HidLibrary version 3.3.40 from NuGet package manager. My operating system is Windows 10 pro 64-bit with build version 10.0.19045.

I am using System.Windows.Forms for my main form that includes Close button to close the device. Whenever, I trigger device close, the software execution triggers the CloseDevice() in the HidLibrary. I debugged the issue and the library is frozen exactly when trying to close one of the handles (ReadHandle) in CLoseDeviceIO(ReadHandle). More specifically, the indefinite blockage is happening in NativeMethods.CloseHandle(handle)

I can see that NativeMethods.CancelIoEx(handle, IntPtr.Zero) is triggered fine and returned successfully.

I tried cloning the library and point to latest master branch, and tried using different versions of .NetFramework 4.5 but nothing worked.

To be fair I have managed to close the device successfully but this wasn't stable at all. It was completely in deterministic behavior in that regards

Check if handle is not null then close it:
if (handle != null) NativeMethods.CloseHandle(handle);
