Reasons

AppListFragment#massIgnore will use a lateinit field apps. If the field is not fully ready, an exception occurs. If I click the Ignore All button even more quickly, another expection like lateinit property apps has not been initialized occurs.

Replay

I am sorry that the video is a bit stuck. Installing more apps on the emulator can help you trigger issues more easily.
