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:
-
Find
state.vscdbfor this project:
C:\Users\<Username>\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.
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.
