Dear @gggggdsfgr,
Thank you for your response.
Unfortunately, we aren’t able to provide the IDs one by one each time.
This time, the issue comes from the question with ID 2198.
There aren’t that many questions in your quiz.?
You can go through them one by one, check which question is causing the problem, and fix it.?
You can either move the question to trash, unpublish it, or delete it from the quiz.
Please check the case, fix all the issues, and let us know if the problem has been fixed or not.
Thank you.
