Minimized code

enum Foo:
  case Bar, Baz

object Foo:
  def render = List(values.tail*).mkString

@main def main = println(Foo.render)

Output

Exception in thread "main" java.lang.ClassCastException: class [LFoo; cannot be cast to class scala.collection.immutable.Seq ([LFoo; and scala.collection.immutable.Seq are in unnamed module of loader 'app')
        at Foo$.render(test.scala:8)
        at test$package$.main(test.scala:10)
        at main.main(test.scala:10)

Expectation

If I disable coverage I get:

Baz
