I just have this in my header

UCLASS()
class RIDERHOT_API UAnimationInstance : public UAnimInstance
{
	GENERATED_BODY()
public:
	UFUNCTION(BlueprintCallable, meta = (BlueprintThreadSafe))
	void UpdateView(){ };

	UFUNCTION(BlueprintCallable, meta = (BlueprintThreadSafe))
	void PlayTest(){ };
	
	
};

Tested out in rider with hot reload
