Error in iOS app when reload an AR scene

[asevillanom]

First time I load a Image tracking AR scene everything works fine but when I exit the ar scene, go to the menu scene (no AR) and load the AR scene a second time a black screen appears. How can I do to solve it?

AR Foundation 4.0.8 & ARkit 4.0.8 Iphone 8 (iOS 13.3) Unity 2019.4 LTS

This is the error that Xcode shows:

NotSupportedException: Update requires a configuration. at UnityEngine.XR.ARKit.ARKitSessionSubsystem+ARKitProvider.Update (UnityEngine.XR.ARSubsystems.XRSessionUpdateParams updateParams) [0x00000] in <00000000000000000000000000000000>:0 at UnityEngine.XR.ARSubsystems.XRSessionSubsystem.Update (UnityEngine.XR.ARSubsystems.XRSessionUpdateParams updateParams) [0x00000] in <00000000000000000000000000000000>:0 at UnityEngine.XR.ARFoundation.ARSession.Update () [0x00000] in <00000000000000000000000000000000>:0

We believe that this may the result of mixing package versions in an incompatible way. Could you please paste in your project manifest.json file under the Packages folder?

This is my manifest.json file:

Anyway, I think I just fixed the problem. I was using "SceneManager.LoadScene (scene, LoadSceneMode.Single); LoaderUtility.Deinitialize ();" when I left the AR scene but I was not adding "LoaderUtility.Initialize ();" when loading again. Now it seems to work fine.
