Hi guys, Today we noticed a weird crash in our Crashlytics dashboard:

🔥 Our current Firebase BoM is 29.1.0 which corresponds to version 20.0.5 of our com.google.firebase:firebase-perf-ktx dependency.

❓ Could it be a class between our different versions of the Firebase Performance Monitoring lib?

🙇 Thanks in advance!
