[Question]: Multi-turn optimization open，After multiple rounds of dialogue, regardless of what questions are asked subsequently, an empty response message will be returned directly

Describe your problem

I encountered a problem regarding multi-round conversations. If the multi-round conversation optimization is enabled, after conducting multiple conversations, no matter what question is asked subsequently, it directly returns an empty response. If the multi-round conversation optimization is disabled, the context of the conversation cannot be connected coherently
