It says, it can not convert from your **UStaticMeshComponent **to USkeletalMeshComponent which is set in your HEADER file
you have created it as
UPROPERTY(EditAnywhere, Category = "Interactable Properties") class USkeletalMeshComponent* InteractableMesh;
So you need to create it as USkeletalMeshComponent, but not like UStaticMeshComponent. Please try this out!
or if you do not need it as a USkeletalMeshComponent you can change it to UStaticMeshComponent and then create it as a UStaticMeshComponent w/o issues
