Have been getting some ActivityThread crashes of which I cannot make much sense. Some of them point to third party libraries which do periodic work like Workmanager, Firebase etc. Root cause of most of these are DeadSystemException which says The core Android system has died and is going through a runtime restart. but is this so common?

This is spread across various Android versions (9 / 10 / 11). There are no repeat crashes for users as such. How do we mitigate this? Thanks!
