Question How to properly restart the XR Session

Hello, currently after a condition is satisfied a I create a new session and do my stuff from a native library (C++) but when I am done with that session I want to go back to Unity. Now, when I go to unity and make CreateSession if needed calls from the OpenXR library I do not render anything even if the program is working and I can get prints from Update function and other stuff. Do you know how can I properly initialize a new session inside Unity?

 

I tried nearly all of the combinations to stop/destroy and start/initialize the session but when I get back to Unity, I can start the session but I cannot see anything, nothing is rendered. Do you have any idea why this can happen?

 

Ok, the thing is I call Stop() then Deinit() and initialize my own session in native side and it works. After my work is done in native side I move back to the Unity side and instantiate a prefab which is a UI Panel says I am done in the native side. In the Awake() of that prefab I call Init() then Start() (because it seems like you can call XRGeneralSettings.Instance.Manager.activeLoader.Init() only in a Start() or Awake() ). Then nothing happens and the program stops. Do you have any idea about why it stops completely ?

 

I have done this but

Code (CSharp):

1. yield return XRGeneralSettings.Instance.Manager.InitializeLoader();

this line does not return even though I've waited for 5-7 mins.

 

I have tried using this and the previous method. But I could not manage start the Update() loop again. Once I stop and deinitialize (or stop systems and deinitialize, doesn't really matter) and do my stuff I cannot seem to be able to turn back to Unity. I have tried to call Initialize() and then Start() but it says you should call this on Awake() or Start(). But I cannot even reach to those states. I even tried loading a new scene, re-loading the current scene or initializing a object( in this one I could call these functions but it didn't change anything only void scene and it is running ?).While stopping and deinit()ing it completes that update() function and then I cannot restart it. I have tried to call the re-initialization functions from various callbacks, even callbacks from UWP's windows such as visibility changed, corewindow.Activated ... It does not work. I think I couldn't find the right time and place to call these functions. If you have any suggestions please let me know.
