I use navigation library and safeargs for passing data. I define argument to fragment like that.

Answer 1

As Christian wrote, adding source set do app gradle file helped. The problem occurs in Android Studio 4.1 and 4.2 for me. In Kotlin DSL:

android {
    ....
    sourceSets {
        getByName("main").java.srcDirs("build/generated/source/navigation-args")
    }
}
