java.lang.IllegalStateException FragmentManager已在执行事务

我正在尝试运行我的应用程序，并将错误作为标题。我不明白为什么我得到这些，因为它似乎是工作较早

下面是我得到的运行时错误，我看不出它为什么不工作，有人能帮我吗 错误：

家庭碎片

  Query firstQuery = firebaseFirestore.collection("Posts").orderBy("timestamp", Query.Direction.DESCENDING).limit(3);

HomeFragment第80行中写了什么请FirstQuery.addSnapshotListener（getActivity（），new EventListener（）{您能在问题中发布代码吗？我知道这是第一段代码，您需要整个类吗？

  Query firstQuery = firebaseFirestore.collection("Posts").orderBy("timestamp", Query.Direction.DESCENDING).limit(3);
            firstQuery.addSnapshotListener(getActivity(), new EventListener<QuerySnapshot>()
