Question Cannot Deinitialize OpenXRLoader after using camera, why?

Hello,
In my project I am using ZXing (https://github.com/micjahn/ZXing.Net/tree/master/Clients/UnityDemo) library to get QR code data, which uses webcam texture. After getting the data I stop the webcam texture and disable the script (also modified the example script to dispose the async function etc.). After that I need to uninitialize OpenXr Loader, I call Stop() on the active loader first and it return true, then when I call Deinitialize() it gives a fatal error. I managed to track the issue to the Internal call

Code (CSharp):

1. Internal_DestroySession();

in the OpenXRLoader.cs in the

Code (CSharp):

1. public override bool Deinitialize()

function. Do you have any idea to avoid this error, or what is causing this?
