I have a small self-contained example to attach.  The short version is, I'm using GSON to deserialize into Kotlin data classes:

data class ServiceResponse(val result: String, val status: Meta)
data class Meta(val success: Boolean)

I reference the "success" field from elsewhere in the project to check if it is true.  This check fails with an exception:

11-06 21:38:37.920 13884-13884/? E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.jebware.r8example, PID: 13884
    java.lang.NullPointerException: throw with null exception

I have keep rules that should prevent the field from being renamed, but looking at the bytecode from the APK, that field has been removed.  I've attached the sample so you can fill in the details.

Using:
android.enableR8=true
android.enableR8.fullMode=false

AGP 3.4.0-alpha02
R8 1.4.3-dev
