Compiler version

3.3.0-RC1-bin-20221128-8fba321-NIGHTLY
3.2.0

Minimized code

Needs minimization, I don't how it can be reproduced in the Vulpix

//> using lib "net.liftweb:lift-json_2.13:3.5.0"

@main def Test = 
  println(net.liftweb.json.NoTypeHints)

Referenced code is in general structured as follows in Scala 2.13

trait TypeHints {
  val hints: List[Class[_]] = Nil
  def components: List[TypeHints] = List(this)

  def + (hints: TypeHints): TypeHints = CompositeTypeHints(components ::: hints.components)

  private[TypeHints] case class CompositeTypeHints(override val components: List[TypeHints]) extends TypeHints {
    val hints: List[Class[_]] = components.flatMap(_.hints)
  }
}

case object NoTypeHints extends TypeHints {
  val hints = Nil
}

Output (click arrow to expand)
