[warn] 	Note: Unresolved dependencies path:
[warn] [sbt-8728] Smorrebrod - the end of Scala 2.13-3.x sandwich
[warn] Scala 3.8+ cannot be used in a Scala 2.13 subproject.
[warn] Dependency resolution failed because scala-reflect or -compiler 3.x does not exist.
[warn] This happens when a Scala 2.13 subproject depends on Scala 3.8+ directly or transitively.
[warn] To fix this, either
[warn]   - Keep Scala 3 subproject or transitive dependency to 3.7 or below, or
[warn]   - Migrate the Scala 2.13 subproject to Scala 3.x
