RecyclerView仅在旋转屏幕后显示

我遇到一个奇怪的问题。最初，我无法理解为什么我的RecyclerView没有显示。但是在我的物理设备上安装后，很明显，旋转屏幕后视图显示的很好。旋转一圈后，该视图将可见并正常运行。

我的片段

class InjuriesFragment : Fragment(R.layout.fragment_injuries) {
    private val injuriesViewModel: InjuriesViewModel by viewModel()

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        injuriesViewModel.update()

        injuriesList.layoutManager = LinearLayoutManager(context)
        injuriesList.setHasFixedSize(true)

        val adapter = InjuriesAdapter {
            Toast.makeText(context, "$it", Toast.LENGTH_SHORT).show()
        }

        injuriesList.adapter = adapter

        injuriesViewModel.injuries.observe(viewLifecycleOwner) {
            val injuries = it.map { it.injury }
            adapter.submitList(injuries)
        }
    }
}

视图模型

class InjuriesViewModel(private val repository: InjuryRepository) : ViewModel() {
    val injuries: LiveData<List<InjuryWithTags>> = liveData {
        emitSource(repository.findAll())
    }

    fun update() {
        viewModelScope.launch(IO) {
            repository.update()
        }
    }
}

适配器

class InjuriesAdapter(private val onItemClickListener: (Injury) -> Unit) : ListAdapter<Injury, InjuriesAdapter.InjuryHolder>(DIFF_CALLBACK) {
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): InjuryHolder {
        val itemView = LayoutInflater.from(parent.context).inflate(R.layout.injury_item, parent, false)
        return InjuryHolder(itemView)
    }

    override fun onBindViewHolder(holder: InjuryHolder, position: Int) {
        val injury = getItem(position)
        holder.occurredAt.text = injury.occurredAt.toString()
        holder.description.text = injury.description
    }

    inner class InjuryHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        val occurredAt: TextView = itemView.occurredAt
        val description: TextView = itemView.description

        init {
            itemView.setOnClickListener {
                if(adapterPosition != NO_POSITION) {
                    onItemClickListener(getItem(adapterPosition))
                }
            }
        }
    }

    companion object {
        val DIFF_CALLBACK = object : DiffUtil.ItemCallback<Injury>() {
            override fun areItemsTheSame(oldItem: Injury, newItem: Injury) = oldItem.id == newItem.id

            override fun areContentsTheSame(oldItem: Injury, newItem: Injury) = oldItem.occurredAt == newItem.occurredAt
                    && oldItem.description == newItem.description
        }
    }
}

这里有人知道出什么问题了吗？

请让我知道我的代码的其他部分是否相关。
