ARFoundation crashes when changing from AR scene to normal scene

Only seems to affect iOS devices.

Is there a way to stop this from happening?

 

ah, thanks!

 

Was there an update on this? It's kind of a showstopper for us as with others commenting in that issue.

When I leave an ARFoundation scene and go back in (game > titlescreen > game) AR flatout stops working and I get a bunch of errors in XCode about planemanager.

Code (CSharp):

1. NullReferenceException: A null value was found where an object instance was required.
2.   at UnityEngine.MonoBehaviour.StartCoroutine (IEnumerator routine) [0x00000] in <filename unknown>:0
3.   at System.Action`1[T].Invoke (.T obj) [0x00000] in <filename unknown>:0
4.   at System.Action`1[T].Invoke (.T obj) [0x00000] in <filename unknown>:0

9. (Filename: currently not available on il2cpp Line: -1)

 

I don't think this is related. Are you unregistering from the planeadded event in ondisable?

Code (CSharp):

1. void OnDisable()
2.         {
3.             ARSubsystemManager.planeAdded -= OnPlaneAdded;
4.         }

 

thank you! All fixed
