Cursor won’t open / loads blank window for a specific project

Support Bug Reports

Hey, this is a known issue. The workspace layout state gets corrupted (usually tied to the “Open Chat as Editor” feature), and on the next launch Cursor can’t restore it, so you end up with a blank window.

Good news for next time: you don’t need to delete the whole workspaceStorage folder. You can delete just one key from the DB and keep your chat history:

  • Find the state.vscdb file at:
    %AppData%\Roaming\Cursor\User\workspaceStorage\<workspace-id>\state.vscdb

  • Open it in DB Browser for SQLite and run:

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

  • Restart Cursor. The project should open normally, and your chat history will still be there.

More context and details on the cause here: Workspace-specific blank window caused by auxiliaryBarVisible

Also, for now, avoid using “Open Chat as Editor”. It’s the main trigger for this issue. The team knows about it and is working on a fix.
