java.lang.NoClassDefFoundError: com.pusher.client.Pusher$$ExternalSyntheticLambda0 on Android API 21-22 anyway

[Yoko999]

What is the issue?

My application with Pusher version 2.4.# crashes on Pusher's initialization on Android API 21-22.
I did like described here, but it doesn't change anything with it.

AGP version 7.4.2
coreLibraryDesugaring("com.android.tools:desugar_jdk_libs:2.0.4")

implementation "com.pusher:pusher-java-client:2.4.4"

Project's compile, target SDK 33
Min SDK 21

Is it a crash report? Submit stack traces or anything that you think would help

It works with Pusher version 2.2.8.
