Numericality validation breaking album update in Ash Framework Book

I'm working through the excellent Ash Framework book (thanks!) on fully updated Ash (i.e. 3.11.3), Elixir 1.19.4, Erlang 28.3 and once I added:
    validate numericality(:year_released, greater_than: 1920, less_than_or_equal_to: &__MODULE__.next_year/0),
      where: [present(:year_released)],
      message: "Must be between 1920 and next year"

and def next_year(), do: Date.utc_today().year + 1
I am now getting an exception when attempting to save an album update. Abridged stacktrace:
[debug] HANDLE EVENT "save" in TunezWeb.Albums.FormLive
  Parameters: %{"form" => %{"cover_image_url" => "", "name" => "In Through the Out Door", "year_released" => "1980"}}
[error] GenServer #PID<0.3218.0> terminating
** (Ash.Error.Unknown)

Unknown Error

* ** (ArgumentError) errors were found at the given arguments:

  * 1st argument: not an atom

  :erlang.function_exported({[AshPostgres.Timestamptz, AshPostgres.Timestamptz], Ash.Type.Boolean}, :evaluate_operator, 1)
  (ash 3.11.3) lib/ash/query/operator/operator.ex:89: anonymous fn/4 in Ash.Query.Operator.do_evaluate/1
  (elixir 1.19.4) lib/enum.ex:1210: anonymous fn/3 in Enum.find_value/3

When I comment out this new validation everything works again. Also the match validation on cover_image_url seems to be working great so only the numericality is breaking.
