After this strings in code all tries to play level crashinfg editor.

UE_LOG(LogTemp, Warning,
TEXT(“Position report reporting for
%s.”), *(GetOwner()->GetName()) );

or

FString ActorName =
GetOwner()->GetName(); UE_LOG(LogTemp,
Warning, TEXT(“Position report
reporting for %s.”), *ActorName );

It does so happened to me. I’m also waiting for the answer of this question.

I’m not sure but when I user this calling method not in ‘Initiate’ method, the problem does not happened.
So maybe the problem is not about what GetOwner() does, but is where and when you call it.
Try to call it in other method like BeginPlay() or etc.
I hope this will give you some help.

I did try running the code on UE4.13.0.
On BeginPlay() it works fine. But when running in the class constructor or in the TickComponent(…) method it crashed.
To recover you have to adjust the code back in the BeginPlay() and compile using an IDE like Visual Studio or XCode. Then the project opens again.

void UPositionReport::BeginPlay()
{
	Super::BeginPlay();
	FString ObjectName = GetOwner()->GetName();
	UE_LOG(LogTemp, Warning, TEXT("Position Report reporting on %s"), *ObjectName);
	
}

or

void UPositionReport::BeginPlay()
{
	Super::BeginPlay();

	UE_LOG(LogTemp, Warning, TEXT("Position Report reporting on %s"), *GetOwner()->GetName());
	
}
