Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this issue is usually related to a large chat history in your project. To solve the problem, try manually deleting most of the history, possibly the oldest chats. You can also try renaming or moving the project. This will help you quickly clear the history.

Additionally, you can delete the history by navigating to this path and sorting the folders by modification date. Choose the one that was used recently, you can delete it or save a backup just in case:

Windows: %APPDATA%\Cursor\User\workspaceStorage
macOS: ~/Library/Application Support/Cursor/User/workspaceStorage
Linux: ~/.config/Cursor/User/workspaceStorage

If your history is important to you, you can try exporting it using this extension:
