Android应用切换底部导航崩溃：未使用setReorderingAllowed(true)

Android应用中，HomeActivity带有底部菜单导航，可打开对应的Fragment。Fragment内部导航正常，但从该Fragment点击其他底部导航项时应用立即崩溃，抛出如下错误：

已尝试以下方法，但均无效：

• 在Fragment的onCreateView()中复用视图：

if (fragmentView != null) {
    return fragmentView;
}

• 在Fragment的onResume()中添加上下文获取逻辑：

var mContext: FragmentActivity? = FragmentActivity()

mContext = this!!.getActivity() as HomeActivity

mContext.bottomItems()

相关代码说明：
首页点击底部导航会打开FirstFragment，FirstFragment包含多个标签页，其中SecondFragment会在FirstFragment.kt的observeResponse()方法中被调用加载。
