Meta XR Simulator Crashes

[menigan]

Hello, Im trying to get the Meta XR Simulator(https://developer.oculus.com/documentation/unity/tools-meta-xr-sim/?intern_source=devblog&intern_con...) up and running but it crashes as soon as I try and launch it.  From the Oculus SDK I am trying to launch the Cubes scene with no luck.

Im using Unity version 2022.3.5f1 along with the latest versions of the Oculus XR Plugin and OpenXR Plugins.  Regardless of which Plugin provider I use(Oculus or OpenXR), the tool crashes Unity as soon as it starts. 

Is there anything I might have missed setting up in order to get this simulator working?  Any help would be much appreciated.

We have the same issue, and have tried several different LTS versions of Unity.  All with the latest Meta XR simulator package and the latest Oculus Integration SDK package. 

None of the sample scenes work with the simulator, they all crash Unity and in the Editor.log from C:\Users\[user]\AppData\Local\Temp\Unity\Editor\Crashes we see this:

For anyone else, we figured out that by installing the SDK and the Simulator using a scope registry instead of downloading them like the tutorials say (e.g. https://developer.oculus.com/documentation/unity/unity-tutorial-hello-vr/) things work.

The trick is that the SDK is found with this scope registry:

Url: https://npm.developer.oculus.com
Scopes: com.meta.xr.sdk

And the simulator is found with this registry:

URL: https://npm.developer.oculus.com
Scopes: com.meta.xr.simulator

Also, when using the latest LTS of Unity (2022.3.7f1) the only versions that don't crash are these ones:

Thanks for posting the answer. I had the exact same issues in Unity 2022.3.7f1 with com.meta.xr.simulator v54.0.1-preview. Downgrading the other com.meta.xr.sdk.utilities package to v54.0.1-preview fixed the crashes for me (i.e. don't use the latest v56.0.0-preview)
