Hey, this is a known issue in versions 2.3.34 to 2.3.35. Your data usually isn’t lost, it just can’t be read because of a DB issue.

Try this workaround:

  • Fully close Cursor (check Task Manager to make sure the process isn’t running)
  • Open %APPDATA%\Cursor\User\globalStorage
  • Find a file like state.vscdb.corrupted.1767...
  • Rename the current state.vscdb to state.vscdb.old
  • Rename the .corrupted file to state.vscdb
  • Launch Cursor

If it doesn’t help, open DevTools (Help → Toggle Developer Tools) and share a screenshot of the console errors. Also, can you create new chats, or is nothing working at all?
