Sketch File Won't Open: Couldn't Load Data
Quick answer
If one document will not open, try opening other files, update Sketch, and check the font and plugin causes. If the app itself is unstable, use the crash fixes.
Most likely fix: Check whether it is the file or the app
How to fix it
Try these in order — the most common fix is first.
1. Check whether it is the file or the app
- Try opening another .sketch file
- If all fail, use Safe Mode (quit, relaunch holding Shift) and see our crash guide

- Sketch changelogs mention fixes for documents that would not open or render
- Update the Mac app (or via the App Store if you installed it there)

- In Finder search for .sketch and sort by Date Modified
- Unsaved files may be kept in ~/Library/Mobile Documents/Sketch (Go > Go to Folder)
- Workspace files: check the Trash in the left panel, or ask an Admin whether it is in a restricted project

- If Sketch is in iCloud Drive, restore files from iCloud on the web (Settings > Restore Files)
- Other sync services may keep earlier versions if set to sync the file
