Enabling/disabling VR with SteamVR 2.0.1

Hello,
as the title says, I'm trying to enable/disable VR between different applications, and I need to do it as many times as I want.

Using https://forum.unity.com/threads/enable-disable-steamvr-on-focus-gain-loss.510914/ will work, but since SteamVR got updated with Actions and Poses etc., I got nasty exceptions since these things don't seem to be handled correctly after disabling VR.
I also tried to disable all actions before disabling, but when I want to come back and enable VR back, nothing will actually work.

Did anyone experience this? How can we fix it?

 

Update:

In order to handle actions and poses when disabling VR, in the Dispose() method of class SteamVR, I added two lines:

Code (CSharp):

1. SteamVR_Input.initialized = false;
2. SteamVR_Behaviour.instance = null;

(I also had to add a public setter for the SteamVR_Behaviour.instance property).

Also, in SteamVR_Behaviour, I added a check inside Update, LateUpdate and FixedUpdate:

Code (CSharp):

1. if (_instance != null) ... // do update

These modifications won't fix the problems actually, because I still have some exceptions when I enable back VR, for example:

Code (CSharp):

1. GetPoseActionData error (/actions/default/in/SkeletonLeftHand): InvalidHandle handle: 1152990670760182193
2. UnityEngine.Debug:LogError(Object)
3. Valve.VR.SteamVR_Action_Pose:UpdateValue(SteamVR_Input_Sources, Boolean) (at Assets/SteamVR/Input/SteamVR_Action_Pose.cs:96)
4. Valve.VR.SteamVR_Action_Skeleton:UpdateValue(SteamVR_Input_Sources, Boolean) (at Assets/SteamVR/Input/SteamVR_Action_Skeleton.cs:75)
5. Valve.VR.SteamVR_Input:UpdateSkeletonActions(SteamVR_Input_Sources, Boolean) (at Assets/SteamVR/Input/SteamVR_Input.cs:487)
6. Valve.VR.SteamVR_Input:UpdateSkeletonActions(Boolean) (at Assets/SteamVR/Input/SteamVR_Input.cs:462)
7. Valve.VR.SteamVR_Input:LateUpdate() (at Assets/SteamVR/Input/SteamVR_Input.cs:352)
8. Valve.VR.SteamVR_Behaviour:LateUpdate() (at Assets/SteamVR/Scripts/SteamVR_Behaviour.cs:224)

...but they are raised just a few times and then they stop. It could be due to some bad timing. Btw, I put an interactable object inside the empty scene just to test if I could still interact with it after disabling/enabling, and it seems that I can.
Also, after disabling and enabling back, I disable/enable also Player and Hands scripts.

Anyway, I wonder if there is an easier and more correct way to achieve a cleaner result.
