我更新了以下库:
- kotlin.reflect to 1.5.31
- room.paging to 2.4.0-alpha05
- room.ktx to 2.4.0-alpha05
，现在我的应用程序的所有功能，使用流和分页的房间对象列表(所有我的RecyclerViews实际上)崩溃与以下模糊的例外:

如果我恢复以前版本的库，一切都可以正常工作。请帮忙!
注意:
不要将这个问题与下面的问题绑定:分页崩溃因为那个问题的答案甚至与这个问题无关，因为Compose包没有被使用，甚至没有包含在我的项目中，而且它不起作用(我测试了它)。
使用Paging 3.1.0-beta01修复，或将Room恢复到稳定的2.3.0。
分页库似乎破坏了3.0之间的二进制兼容性。x和3.1.0，房间2.4.0-alpha05+使用更新后的合同。这很可能与新的room-paging库有关。他们在发布说明中讨论了很多新的分页互操作要求，但我没有看到任何要求严格的版本要求。https://developer.android.com/jetpack/androidx/releases/room 2.4.0-beta01
