Cannot Access AI Pane

Bug Reports
1

Describe the Bug

The AI Pane (chat) is currently closed. When I try to open it, either by clicking the button or using the keyboard shortcut (⌥⌘B), the app freezes and becomes unresponsive.

The only way to get it working again is to force-quit the app and reopen it, but I can never access the chat.

Sometimes, a pop-up appears saying “The window is not responding”.

Steps to Reproduce

  • Open Cursor
  • Click the “Toggle AI Pane” button on the top right
  • Cursor will become unresponsive

Expected Behavior

The AI Pane is supposed to open and the user should be able to access the chat.

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.

Thanks for the suggestion. If I can’t access the AI Pane, how can I delete old chats? Is there a way to do it from Finder?

Yes, you can delete the history from Finder by navigating to this path and sorting the folders by modification date. Select the one that was used recently and delete it.

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

That worked. Thanks so much for the help and quick responses!
