Hey, thanks for the report. You’re right, this looks like the same issue caused by a large chat history in state.vscdb.

How to fix on macOS:

  1. Close Cursor
  2. Delete the workspace database files:
Windows: %APPDATA%\Cursor\User\workspaceStorage
macOS: ~/Library/Application Support/Cursor/User/workspaceStorage
Linux: ~/.config/Cursor/User/workspaceStorage
  1. Restart Cursor

To preserve chat history before deleting: install the SpecStory extension and export your chats.

Let me know if this resolves the hanging issue.
