scala-collection-compat was declared with %% which doesn't carry the .nir files necessary for Scala Native.
Moreover, it was always added since the correct switch should be scalaVersion.startsWith("2.12.") not !scalaVersion.startsWith("3.0")

Workaround

Until this gets merged and published you can exclude the wrong scala-collection-compat artifact and manually add the correct version to your libraryDependencies

libraryDependencies ++= Seq(
  ("com.outr" %%% "scribe" % "3.14.0")
    .excludeAll("org.scala-lang.modules" %% "scala-collection-compat")
)

libraryDependencies ++= (
  if (scalaVersion.value.startsWith("2.12.")) {
    List("org.scala-lang.modules" %%% "scala-collection-compat" % "2.12.0")
  } else {
    Nil
  }
)
