This crash is happening in our production app. I haven't been able to reproduce it locally, but looking at WorkManager's source, the cause seems pretty straightforward.

Here's the source for ListenableWorker.stop for version 2.5.0-beta01:

public final void stop() {
    mStopped = true;
    onStopped();
}

And here's the source for ConstraintTrackingWorker.onStopped for version 2.5.0-beta01:

@Override
public void onStopped() {
    super.onStopped();
    if (mDelegate != null) {
        // Stop is the method that sets the stopped and cancelled bits and invokes onStopped.
        mDelegate.stop();
    }
}

stop calls onStopped which calls stop and so on. My assumption is that one of these two methods should check if the worker has already been stopped before calling each other again.
