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.

If reinstalling helps, can’t we get rid of the chat files locally? Or at least there must be some files, that tell cursor to load the chat history. Can’t we make cursor forget a repo?

Note, I’m facing a similar issue.

You can rename the project folder and reopen it. that will remove the chat history.

As you saw in another thread the SpecStory extension alows you do export chats to MD files if you wanna keep them.

I tried reinstalling, and that worked. Will try SpecStory if needed. Currently, I don’t see a use case.
