I am working on a React Native app, specifically on the iOS native module with RealityKit. An apparently unexplainable error keeps happening at runtime, as you can see from the following image: Crash log from XCode When I try to retrieve the position of my AnchorEntity relative to the world space (so using relativeTo: nil), it triggers a runtime exception during some of its internal calls: CoreRE: re::BucketArray<unsigned short*, 32ul>::operator[](unsigned long) + 204 As you can see from the code, my AnchorEntity is not null as there is a guard check. I also tried to move that code into an objective c static function in order to use @try @catch and catch runtime exceptions, to later realise that RealityKit is not compatible with ObjectiveC. Do you have any idea/suggestion on how to fix it/prevent it?
