Cursor displays a blank layout after opening the project

Hey, thanks for the report. This is a known issue with the workspace layout state. Switching between layout modes can leave an invalid state in the workspace database.

Workaround without reinstalling:

  1. Find state.vscdb for this project:
    C:\Users\<Username>\AppData\Roaming\Cursor\User\workspaceStorage\<workspace-id>\state.vscdb

  2. Open it in DB Browser for SQLite and run:

    DELETE FROM ItemTable WHERE key = 'cursor/editorLayout.auxiliaryBarVisible';
    
  3. Restart Cursor.

If you don’t want to deal with SQLite, you can just delete the <workspace-id> folder for this project. You’ll only lose the chat history for that workspace.

For now, I’d recommend avoiding “Open Chat as Editor”. This feature often triggers this issue.
