Why Submission #287572 faild?

  1. Submission #287572 is failed without any logs. It has successed before.
  1. AIcrowd | Multi-turn QA | Submissions #287033 Why the inference is completed but the score not update on the leaderboard?

I just want to know the reason why my submission failed. To be honest, I have not successfully submitted the second and third questions in stage two so far. After one failure, I restarted and got a normal score, but it was not updated on the leaderboard (see AIcrowd | Multi-turn QA | Submissions #287033. I asked in the discussion, but no one responded. Every other subsequent submission was stuck at 18%. Please help me to see the reason for the failure (only the original logs is ok for me). If it is my problem, I will modify it, but I do not know the reason at the moment. Do I have to waste the number of submissions to try again and again?
