Hey, thanks for the report.
Known issue: workspace storage can get corrupted after the chat crashes.
Workaround for macOS:
- Fully quit Cursor
- Open
~/Library/Application Support/Cursor/User/workspaceStorage/ - Find the folder for the workspace you need (you can sort by “Date Modified”, it should be the most recent one)
- Delete
state.vscdbandstate.vscdb.backupfrom that folder - Start Cursor and open the project again
Downside: you’ll lose chat history and open tabs for that workspace.
