Riaan, thank you! I've been wrestling with this for months now, and your diagnosis is spot on. In any case, at least for me, deleting the records fixed everything.
I think you're right that the issue is triggered by unlocking course completion criteria. I don't have a very strong understanding of the moodle codebase, however, so it's difficult for me to speculate much beyond that. I will see what I can do to reproduce the error, though, now that I know how it's fixed!
