open class A {
  
  @Composable
  fun test(
    x: String,
    lambda: @Composable () -> Unit = {} // runtime exception below is caused by this parameter 
  ) {
     Text(x)
     lambda()	
  }

}


open class B  : A {

}


open class C : B { // C -> B - > A

  @Composable 
  fun anotherTest() {
    test("1") // while incremental compile (change for example "1" -> "2") throws runtime error: java.lang.ClassCastException: class androidx.compose.runtime.internal.ComposableLambdaImpl cannot be cast to class kotlin.jvm.functions.Function0 
  }

}

Compose Desktop version 1.3.0-alpha01-dev831

Edit: In my case A, B are located in one Gradle module, while C in another. But may be it will reproduce when all classes in the same module (I didn't check it).
