How to reproduce?

Maybe you can provide code to reproduce the problem? https://scastie.scala-lang.org/Fy5fl0keRXWtP8i5bSCymA

Additional information If reduce field numbe of case class StandardAreaInfo or TwinNode by 1，for example, comment country:String or city:String, or realSceneID:UUID or coverImage:Option[String] , the errors disappears

I have the same Problem: Tapir version: 0.18.3 Scala version: 3.1.0

To a certain point I could work around this problem with

    scalacOptions ++= Seq(
      "-Xmax-inlines",
      "50" // is declared as erased, but is in fact used
    )

Compiling gets really slow though.

I got this from here https://github.com/lampepfl/dotty/issues/13044

Maybe this is related.

Same issue here, however I worked around it by using Schema.derived[T]

See https://github.com/softwaremill/magnolia/issues/374 - a bit minimized, but still mysterious

@Centaur your particular problem is solved by bumping max-inlines as @pme123 suggested (thanks!). Question remains, can we do something in magnolia about it, or maybe Scala should bump the inlining limit. These classes aren't that complicated
