The release variant not work

I just follow this post on medium and make some feature with same structure.
on debug variant everything is fine, but on release variant and upload it to playstore didn't work as expected.

I use latest dagger version : 2.42

I guess this line return null instance :

android-dynamic-code-loading/app/src/dagger/java/com/google/android/samples/dynamiccodeloading/di/BaseDagger.kt

Line 63 in 36a30e8

    
           val provider = Class.forName(PROVIDER_CLASS).kotlin.objectInstance as StorageFeature.Provider

I have asked on SO and not have answer yet. Thanks in advance.
