我认为这可能与问题中的通配符有关。
如有任何帮助，我们将不胜感激。谢谢你抽出时间。
看起来这是一个错误，特别是在使用通配符时
这是的代码行
$nbofquiz = $DB->count_records('quiz_slots', array('questionid' => $qu->id));
https://github.com/moodle/moodle/blob/v4.0.2/question/type/calculated/questiontype.php#L1762
该错误是由Moodle 4的升级引起的，该升级删除了Moodle票证MDL-71696 的quiz_slots表中的questionid字段
MDL-71696 mod_quiz：测验更新和行为覆盖
$field = new xmldb_field('questionid');
// Conditionally launch drop field questionid.
if ($dbman->field_exists($table, $field)) {
$dbman->drop_field($table, $field);
}

我在Moodle bug追踪器上进行了快速搜索，并在6月份被报道。

集成中有一个修复程序，看起来他们昨天已经完成了测试，所以应该很快就会提供
