Guys, maybe i’m late, but i found a great, simple and very effective solution that stops behaviour tree work without multithreading.
You just need to open BTTask_Wait class and see that there is no need to recreate a bicycle
I put this code and it suddenly worked

UBTTAttackActor::UBTTAttackActor()
{
	NodeName = "Attack Target Actor";
	bNotifyTick = true;
}

void UBTTAttackActor::OnGameplayTaskActivated(UGameplayTask& Task)
{
	IsWeaponWorkComplete = false;
}

EBTNodeResult::Type UBTTAttackActor::ExecuteTask(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory)
{
	SelfActor = Cast<AUCGAIPawn>(OwnerComp.GetBlackboardComponent()->GetValueAsObject(SelfActorKey.SelectedKeyName));
	TargetActor = Cast<AUCGBasePawn>(OwnerComp.GetBlackboardComponent()->
		GetValueAsObject(TargetActorKey.SelectedKeyName));
	TargetActor->GetMovementComponent()->StopMovementImmediately();

	UUCGAIWeaponComponent* AIWeaponComponent = Cast<UUCGAIWeaponComponent>(SelfActor->WeaponComponent);
	// Subscribe on weapon delegate
	AIWeaponComponent->GetWeapon()->OnWeaponWorkCompleteDelegate.AddUObject(this,
		&UBTTAttackActor::SetWeaponWorkIsComplete);
 // Set the function that must be called in the end

	// Starts the weapon work
	AIWeaponComponent->AttackAutomaticaly();

	// Shows Behaviour Tree that work hasnt done
	return EBTNodeResult::InProgress;
}

void UBTTAttackActor::TickTask(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory, float DeltaSeconds)
{
	// Checks if weapon attacked, stopped and reloaded
	if(IsWeaponWorkComplete)
	{
		IsWeaponWorkComplete = false;
		// Finishing the Task, continue BT workflow
		FinishLatentTask(OwnerComp, EBTNodeResult::Succeeded);
	}
}

void UBTTAttackActor::SetWeaponWorkIsComplete()
{
	// Sets the value that checks in Tick
	IsWeaponWorkComplete = true;
}
