Research direction
Start by reproducing the IllegalArgumentException and trace the call path from GreedyScheduler.onExecuted through ConstraintTracker.removeListener to NetworkStateTracker.stopTracking. Inspect the referenced WorkManager classes and Android receiver lifecycle; done means the reported crash no longer occurs during constraint tracking cleanup.
Written by the indexing model from the issue text.
