Same problem here. Moodle 4.4.1. It happened on quiz question statistics page /mod/quiz/report.php?id=432&mode=statistics&slot=6 after I changed the text of answers, although I didn't add or delete any answers.

Exception - Call to a member function has_subparts() on false

Debug info:
Error code: generalexceptionmessage


Stack trace:

Do you have any news here, or maybe a workaround to fix this issue? I'm having the same issue on Moodle 4.5
