To Reproduce
Steps to reproduce the behavior:

1. Go to build.gradle.kts (:demo) file
2. set debug build type config with "isMinifyEnabled" as true. Add or update following lines in buildTypes {}
   getByName("debug") {
   isMinifyEnabled = true
   proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
   }
   getByName("release") {
   isMinifyEnabled = false
   proguardFiles(getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
   }
3. sync and run app in device
4. App crashes with an exception :
