IncompatibleClassChangeError

scalaJSLinkerConfig ~= {
      _.withESFeatures(_.withESVersion(ESVersion.ES2020))
    }
ThisBuild / scalaVersion := "2.13.11"

      "dev.optics" %%% "monocle-core"  % "3.2.0",
      "dev.optics" %%% "monocle-macro" % "3.2.0"

i'm running this scalatest scala.js test from intellij:

case class Chat(history:List[String])

chat.focus(_.history).replace(Nil)

It doesn't like to run the focus(_.history):

An exception or error caused a run to abort. This may have been caused by a problematic custom reporter.
java.lang.IncompatibleClassChangeError: class com.my.FooBarSpec$$anon$1 can not implement monocle.PLens, because it is not an interface (monocle.PLens is in unnamed module of loader 'app')
