Hey @wwwjf. Looks like the report got posted twice, so I’ll close this copy to keep the discussion in one place.
Let’s continue in your first thread: Files zeroed + Local History rewritten empty on startup — 3.23.12, macOS, no force-quit (25 events, 5016 empty snapshots sourced "Undo Create Diff"). I’ll reply there with next steps, including how to stop it from getting reset again and how to restore the files.
Thanks for the detailed logs and timing info, they really help.
