Download fails on some courses

Description of the bug

When I try to download the courses of the moodle of my school, I get an error (moodle-dl --verbose --log-to-file)

My school updated moodle over the summer holidays, I don't know the old version. This is a minimal example with only one small course. The error occurs only when trying to download some courses, but not others. I could not identify which feature of the course breaks the downloader. If you need any more information, I would be happy to provide it.

Expected behavior

moodle-dl downloads the course contents and exits without error
