I was in the middle of a multi-day chat session when prompted to update Cursor this morning. After update, I’m unable to access the chat at all and cursor keeps crashing repeatedly with the following error code:

The window terminated unexpectedly (reason: ‘crashed’, code: ‘5’)

I’ve attached a GIF so you can see the doom loop I’m caught in.

Hey, it seems the error is related to having too much chat history. If losing the history isn’t critical for you, you can try reinstalling Cursor. However, if you need to keep it, you can save it in Markdown files using an extension.
