Caused by: java.lang.AssertionError: IR backend shouldn't call KotlinTypeMapper.mapType: AppMain

Well that's sad, just when I was trying to add Compose to an existing app to be the first to use it at production, I get this with 3 different versions of Kotlin, looks like Play Store will be compose free for some more time 🧌. PS: Fixed by commenting the following lines:

buildFeatures {
    compose = true
}

thanks! that one fixed the build for me. There are some libraries that not play nice with the compiler yet but that is easy to handle
