Reading from this dictionary in CalendarView.body prior to the crash is legit (main thread)
But there can also be writes on background threads originating in MediaCalendar.fetchMovies
Solution: mark the dictionary as @MainActor, mark any method that uses it (e.g. maybeInsertMovie) as @MainActor. Consider marking all view models as @MainActor by default, use nonisolated as an exception where needed.
