Compiler version

crashes on both 3.3.0 and 3.5.0

Minimized code

object CompilerCrash {
  trait Scope {
    private type Event = String

    case class Cmd(events: List[Event])
  }

  new Scope {
    val commands = List(
      Cmd(List("1", "2"))
    )
  }
}

Also the same code fails to compile here: https://scastie.scala-lang.org/migesok/VCm2LTz1ToWFmuG5mYBblw/1

It compiles fine if private modifier is removed.

Survive inaccessible types when computing implicit scope (#21589)
