PSA: You may need to add -keep class io.karn.notify.entities.*

Just updated to 
Android Studio Bumblebee | 2021.1.1 Canary 3
Build #AI-211.7442.40.2111.7518594, built on July 2, 2021

And had to add

-keep class io.karn.notify.entities.*

to my proguard files

Without that line it ket crashing at  payload.bubblize at NotificationInterop.kt
