What to do if I got

The root cause java.lang.RuntimeException was thrown at: org.jetbrains.kotlin.backend.jvm.codegen.FunctionCodegen.generate(FunctionCodegen.kt:48)

With kotlin serialisation?

The best thing to do would be to open a YouTrack ticket with a reproduction if you have one. The entire stack trace would be good as well. Any crash like this is automatically a bug in the compiler.
