This has been discussed already in numerous posts.

It started affecting me recently on Windows with a long chat.

Apparently, deleting all your chats is the workaround. But perhaps just removing your most recent chats may work. You can do this on the “chat history” panel.

What I did was stop cursor and remove the most recently modified directory in:  
`C:\Users\stk\AppData\Roaming\Cursor\User\workspaceStorage`

That blew away my pane setting layout and chats, but that’s about it.

Hope that is helpful.
