Error in ChatGPT, No option enter the message after encountering an error

I have encountered an error while using chatgpt.
I copied my html in the message and it exceeded the message limit during the conversation. It shows the error message and entire conversation become ended as there is no option to enter the next message. Only give me an option to regenerate response, the same error again.

Please check and rectify the error, if you can provide user the option to enter the next input.
