Cursor IDE jammed - trying to load chat and IDE freezes

Describe the Bug

At some point the chat window suddenly froze down and the whole IDE stopped responding. When reopening the same project the IDE freezes in the same state, the chat window seems to be loading but it is not responding.
Top menu items in the osx header are responsive but not selectable (no menu items can be opened) and none of the IDE elements are responding.

Steps to Reproduce

Something probably caused the chat to freeze or break down. I am not able to resolve it for this specific project (works normally for my other projects). I did not yet try to reinitialize the repo into a new folder. The chat was quite long so I assume that could have been one factor here.

Expected Behavior

IDE should open and respond for user interactions.

Additional Information

Is there some local chat cache that could be cleared?
Is there a possibility to remove the earlier chats from web?

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, just ran into this problem. I couldn’t figure out the source of the problem so my workaround was to just delete the latest chat.

I found it in ~/Library/Application Support/Cursor/User/History. I simply deleted the latest folder and now the app will open for me again.

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:

macOS: ~/Library/Application Support/Cursor/User/workspaceStorage

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

I’ve run into this issue a few times over the past few days. It usually occurs when I try to apply changes to a file via the Ask mode (small chats & large chats). When I try re-opening the repository I can click around for a few seconds until the chat starts to initialize, and at that point I am stuck again.

I have found that going to your chat history right when the window opens again and deleting the most recent chat resolves this issue for the current repo you are in. Though as @garrett92895 mentioned, clearing that latest chat in the ~/User/History is probably a better approach since the UI may lock up before you can delete the chat.

I’ve found this to be the issue. When applying question in ask mode. I ended up going into the App data and deleting the conversation. Others have stated other good way to get around this issue.

Same here getting lot of “not responding”
