Why Kotlin Android APP gets java.lang.VerifyError KotlinNamesAnnotationIntrospector on KitKat

I'm using Android Studio 3.2.1 on Ubuntu 16.04 with Kotlin plug-in 1.3.11. If I deploy my app with Android Studio to a virtual device with KitKat (API 19), the app is started but immediately crashes. The OS says "Unfortunately, has stopped. I see in the debugger console the following exception:
W/dalvikvm: threadid=1: thread exiting with uncaught exception (group=0x9ccbbb20)
