Editor and Game window objects disapper - IndexOutOfRangeException: renderPassIndex

Unity Engine

hi, community.
I have meet this issue recently and not sure is it a bug or sth else? I use the newest version of Unity(2019.3.14) in URP mode and try to develop an Oculus quest. After I run the Unity for more then 10 or 20 minute.When I click play to enter the PlayMode. It will suddenly come out this message:

ndexOutOfRangeException: renderPassIndex

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

and then in the scene window and game window, everything disappear and just show the background color.When I select an object on Hierarchy I can show the transform arrow on the scene but without the object. No matter what I do( Exit playmode or enter playmode), this issue still exist.I have to restart this editor then everything fix.

Hope anyone can give some tips? It’s a very annoying issue

Hello
I have a similar error message :

When I press play, the image in the VR headset is fixed and rotated in the sky direction. But in the same project, when I try in an other scene it works… I don’t understand why I have this bug and why only in one scene…
I saw that there were no response in the last message but I am a bit desperate after many days working on it…

For information I am working with Unity 2022.3.10f1, with a Pico 4 headset in URP mode.

Hello,

Can you tell us which plugin/package are you using for XR support?

Hello,
Thanks for the response.

I use the PICO Integration sdk (PXR_SDK) with the XR integration toolkit, as recommended in PICO tutorials.

Since my last message I found a temporary solution, I deactivated all the gameObjects in my scene at Start and then reactivate them, it works but if I add another camera in the scene the render of the camera in the headset stops.

It seems to be a performance problem with my scene, I am trying to work on it. In addition, I noticed that the camera render was better in a builded app than in the play mode in Unity.
