My conversation was suddenly deleted for no reason, how do I recover it?

I was typing a normal message to ChatGPT, the website was lagging as usual so I was typing in advance before the message displays in the message box, then I see only the second half of my message, and I’m on the page you’re on when you start a new conversation, and the conversation I was just in is gone. I tried going to the link three times or close, it didn’t work, it said unable to load, luckily I had an old tab of the conversation open, so I copied all of the text from there. How do I get the conversation back?
