Frozen chat - non-responsive editor in specific repo

Describe the Bug

Using an agent inside a chat, I asked an question & while working on it, it just crashed. I can’t use Cursor in that specific repository because it just stops working. Everything freezes up - getting a sys dialog, asking me to just reopen/keep waiting for the window to be responsive.

Steps to Reproduce

I can’t reproduce it - I’ve asked a chat to change some files. I’m doing this in Golang repository if it helps.

Operating System

MacOS

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:
