Problem loading a conversation with a custom GPTs

I have the GPT plus version, I’ve already managed to create some GPTs, however I can’t chat with them for a long time due to the message “very long conversation” or “huumm something went wrong”, when I leave the GPT chat and return to it later conversation does not load and only the message “Unable to load conversation” appears. Would it be possible for someone to tell me how to resolve this error or if I’m making an error when using it?
