当配置发生更改并且我的Activity和Fragment因此被重新创建时，我的nav Graph作用域ViewModel不可用，而Fragment已经被重新创建。
片段似乎在navGraph之前被重新创建。
我使用这段代码从我的Fragment初始化我的navGraph作用域ViewModel：

private val myViewModel: MyViewModel by navGraphViewModels(R.id.nav_graph_id)

如果我尝试在Fragments onViewCreated函数中使用myViewModel，我在配置更改后得到一个IllegalArgumentException。

java.lang.IllegalArgumentException: No destination with ID <destination id> is on the NavController's back stack

我该怎么办？
I have already checked that my ID isn't used anywhere else.
