I am able to set up a UWidgetComponent with a user widget (via SetWidget()) no problem, but when I use SetSlateWidget() instead, I get EXC_BAD_ACCESS in UWidgetComponent::TickComponent(). Am I missing something?

    UWidgetComponent* StatViewComponent = NewObject<UWidgetComponent>(GetOwner(), UWidgetComponent::StaticClass());
    StatViewComponent->RegisterComponent();
    
    StatViewComponent->AttachToComponent(GetOwner()->GetRootComponent(), FAttachmentTransformRules(EAttachmentRule::KeepRelative, EAttachmentRule::KeepRelative, EAttachmentRule::KeepRelative, false));
    
    SAssignNew(StatView, STextBlock).Text(FText::FromString(GetName()));
    
    StatViewComponent->SetSlateWidget(StatView);
    StatViewComponent->SetWidgetSpace(EWidgetSpace::Screen);
