The function called "Wait Input Release"

I found that doing:

TArray<UGameplayAbility*> Instances = AbilitySpec->GetAbilityInstances();
for (auto Instance : Instances)
{
	FPredictionKey InstancePredictionKey = Instance->GetCurrentActivationInfo().GetActivationPredictionKey();
}

Would show the correct prediction key

The issue can be fully resolved by changing Lyra’s code to:

void USandboxProjectAbilitySystemComponent::AbilitySpecInputReleased(FGameplayAbilitySpec& Spec)
{
	Super::AbilitySpecInputReleased(Spec);

	if(Spec.IsActive())
	{
		TArray<UGameplayAbility*> Instances = Spec.GetAbilityInstances();
		const FGameplayAbilityActivationInfo& ActivationInfo = Instances.Last()->GetCurrentActivationInfoRef();
		FPredictionKey OriginalPredictionKey = ActivationInfo.GetActivationPredictionKey();
		InvokeReplicatedEvent(EAbilityGenericReplicatedEvent::InputReleased, Spec.Handle, OriginalPredictionKey);
	}
}
