Regression: Tested in UE5/Release-5.0, this issue did not occur so it is a regression.
Actual Result: Package shows a black screen while trying to scan room and an Ensure populates the logs
Expected Result: Package runs properly on the Android device
Ensure condition failed: CurrentGCObject->GetReferencerName() != FGCObject::UnknownGCObjectName [File:D:/build/++UE5/Sync/Engine/Source/Runtime/CoreUObject/Private/Misc/GCObjectReferencer.cpp] [Line: 168] Please make sure all FGCObject derived classes have a unique name by overriding FGCObject::GetReferencerName() function. FGCObject::GetReferencerName() will become pure virtual in the next engine release. See callstack for details.
