Not sure if you submitted the feedback, but the workaround for the moment is in the release notes.
#Preview can’t reference symbols in Swift type extensions when they are defined in the same module as the Preview (110671628)
Workaround: Revert to using PreviewProvider, or copy the implementation of the extension directly in to the #Preview itself or make it a global symbol

After deleting an item, SwiftUI may attempt to reference the deleted content during the animation causing a crash. (109838173)
Workaround: Explicitly save after a delete.
Thanks! That worked. I suspected I was overlooking something obvious, and it was that I forgot the context in Previews.
