Kimi Code Stuck on "Processing" and Doesn't Respond

What feature would you like to see?

I have an issue where Kimi Code doesn't respond.

Yesterday, I set up Kimi Code in VS Code and connected it to the Unity MCP. I started the server, and everything worked fine. We were able to communicate and completed the setup successfully.

After that, I tried a prompt. Kimi started thinking and generating code, but after a while it only displayed "Processing" in the Kimi chat window. From that point on, Kimi stopped responding.

I restarted VS Code, restarted the MCP server, and even tried starting a completely new chat, but the issue persists. Every time I send a prompt, it immediately gets stuck on "Processing" and never returns a response.

There are no obvious error messages in the chat window, and as far as I can tell, the MCP server is running normally.

Has anyone experienced this issue before or knows how to fix it? Any help would be greatly appreciated.

The reported entry points are VS Code, Unity MCP, and Kimi Code; start by reproducing the stuck “Processing” state with a new chat after restarting both services. Done means a prompt receives a response, or the failing integration and an actionable error are identified.
