What issue are you seeing?

During a normal chat, the assistant entered an unproductive loop repeating: "uau. e o what?" many times in a row, without new useful content, and did not return to normal response flow.

What steps can reproduce the bug?

Uploaded thread: 019fa629-a69c-7e10-bbf5-baf37f888587

What is the expected behavior?

Single, clear responses with no meaningless repetition or infinite loop.
