Cannot create a file when that file already exists. (0x800700B7)

This 2 line program will get an error with version 3.4.0-preview

using Microsoft.WindowsAPICodePack.Sensors;
var list = SensorManager.GetAllSensors();

I received the following error:
System.Runtime.InteropServices.COMException: 'Cannot create a file when that file already exists. (0x800700B7)'

System.Runtime.InteropServices.COMException

I downloaded the source and am getting the error here:

internal ISensor InternalObject
{
    get => nativeISensor;
    set
    {
        nativeISensor = value;
        SetEventInterest(new Guid(Guids.EventSystem.StateChanged));
        nativeISensor.SetEventSink(this);
        Initialize();
    }
}

System.Runtime.InteropServices.COMException: 'The requested resource is in use. (0x800700AA)' on line 572 of Sensor.cs
(which is "nativeISensor.SetEventSink(this);"

This exception was originally thrown at this call stack:

Microsoft.WindowsAPICodePack.Sensors.Sensor.InternalObject.set(Microsoft.WindowsAPICodePack.COMNative.Sensors.ISensor) in Sensor.cs
    Microsoft.WindowsAPICodePack.Sensors.SensorManager.NativeSensorCollectionToSensorCollection<S>(Microsoft.WindowsAPICodePack.COMNative.Sensors.ISensorCollection) in SensorManager.cs
    Microsoft.WindowsAPICodePack.Sensors.SensorManager.GetSensorsByCategoryId(System.Guid) in SensorManager.cs
    Microsoft.WindowsAPICodePack.Sensors.SensorManager.GetAllSensors() in SensorManager.cs
    Program.<Main>$(string[]) in Program.cs

This change seems to fix it but I'm not an expert at this api. (educated guess). The change is to only call the SetEventSink if
it is supported.

        set
        {
            nativeISensor = value;
            SetEventInterest(new Guid(Guids.EventSystem.StateChanged));

            nativeISensor.SupportsEvent(new Guid(Guids.EventSystem.StateChanged), out bool isSupported);
            if(isSupported)
                nativeISensor.SetEventSink(this);
            Initialize();
        }
