I have found the answer to my problem in this post:

> Hello Unreal Engine Community, I’m encountering a problem with my Unreal Engine 5 project and could really use some help. I have a Blueprint named BP\_VRPawn which is derived from a C++ class AVRPawn. The main issue is that the Skeletal Mesh representing the hands is not being attached to the MotionControllers. Another issue is that the first time I open the folder containing BP\_VRPawn, or the first time I open the Blueprint itself, the Visual Studio debugger stops, and I receive the following l…

My understanding of the problem is as follows:

In the constructor of my `UCameraMovementComponent` I set attachement to `this`:

```auto
UCameraMovementComponent::UCameraMovementComponent()
{
	PrimaryComponentTick.bCanEverTick = true;
	PrimaryComponentTick.SetTickFunctionEnable(true);

	mesh_ = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Mesh"));
	mesh_->bAutoActivate = true;
	mesh_->bAutoRegister = true;
	mesh_->SetupAttachment(this);
}

```

When the CDO of my class is constructed, `this` is pointing to the CDO and not the specific instance of my class. Since `mesh_` is a UPROPERTY it will be get replaced in the actual instance after construction with the version from the CDO. This means my class instance has a `mesh_` that is attached to the CDO, and not my instance.

To Solve this issue I need to reattach the `mesh_` to the correct parent when the component is registered (after the CDO values are copied)

```auto
void UCameraMovementComponent::OnRegister() {
    Super::OnRegister();
    this->mesh_->AttachToComponent(this, FAttachmentTransformRules::KeepRelativeTransform);
}

```

With this addition the component works as expected.
