I deleted my project chat. How can i recover?

I accidentally deleted my project’s chat in v0. I thought the button would only remove part of the chat, but it ended up deleting everything. The project is still active, but I can’t edit it anymore. How can I recover it, or start a new chat to edit the project again?

Also, what happens when the chat context limit is reached? I hit the limit and couldn’t send anything else.

What should I do in such cases? Can I no longer edit the project?
