Your question is Handling a Project Failure. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe a time you failed.
Be specific about the situation, your responsibility, what you did after recognizing the failure, and the outcome. Focus on how you communicated, corrected the issue, and changed your approach afterward.
