I can't keep chatting. My chat disappears after getting error messages

I have this long chat, in which after I send any message I receive an error.
ChatGPT ignores the error and continues chatting, but after that my conversation vanishes (the part after the error message).

I have not been able to continue my conversation.

On PC I’ve been getting ‘network error’ message.
On my PC, ChatGPT crashed (as in the browser asked to close it because it wasn’t responding).

On Iphone I’ve been getting ‘hmm… something seems to have gone wrong’ error message and a button to retry.
I retried many times, but nothing changed.
I’ve reinstalled the app on my Iphone, nothing changed.
I also tried switching from my wifi to cellular network on my Iphone,
nothing changed.

I have the exact same error right now. Did you find a solution or what the problem was?
