Describe the problem

Crashlytics is reporting 80 users experiencing a null pointer exception When calling trace.stop(); We haven't seen this during development and trace object itself itsn't null; the crash comes in the obfuscated firebase code. Is there anything we can to prevent the crash?

Fatal Exception: java.lang.NullPointerException
Attempt to invoke virtual method 'com.google.android.gms.internal.firebase-perf.zzcr com.google.firebase.perf.internal.zzq.zzbf()' on a null object reference
com.google.firebase.perf.internal.zzq.zza (zzq.java:39)
com.google.firebase.perf.metrics.zzd.zzcd (zzd.java:20)
com.google.firebase.perf.metrics.Trace.stop (Trace.java:87)

app-level build.gradle:

implementation 'com.google.firebase:firebase-perf:19.0.0'
...
apply plugin: 'com.google.firebase.firebase-perf'

I don't see anything in the Trace docs about NPEs, and didn't find any mention of this in the issues for this repo.

I also looked at the release notes for Performance Monitoring for 19.0.1, 19.0.2, 19.0.3, 19.0.4, and 19.0.5 for mention of a NPE to see if upgrading would fix the issue, but don't see any mention of it.
