Crash with Proguard in Release Mode

Hi!

Implementing the latest SDKs, running the app in Proguard mode causes a crash that can't be traced back due to obfuscation.
Executing the code without Proguard works just fine.
The error occurs, when I'm clicking the "start a conversation" button.

I have followed the recommended settings for Proguard and R8

Even with over-configuration, definitely covering all cases, the error still occurs.

Proguard Config:

-keep class zendesk.** { *; }
-keepnames class zendesk.** { *; }
-keep class sun.misc.Unsafe { *; }
-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase
