A NPE was reported for ConversationsListActivity.kt:537
Adapter is accessed with !! while it is not safe to access in term of lifecycle.
So there could have been a race condition.
The overall problem is not solved and may even have to wait for migration to Compose.
This is just a quickfix for v21.0.0
Reported crash was :
Exception java.lang.NullPointerException:

without this fix, the scope may not have been initialized which threw the following exception:
