Moodle plugin - Cannot edit or create Question sets or Columns - throws errors
Environment: Moodle 3.9, running latest H5P plugin (2020020500) and latest libraries (refreshed nightly, via CRON)
Summary: At some point last week, certain H5P activity types such as Question Set (1.17.2) and Column Column (1.12.0) stopped being editable and started throwing errors (details lower). These activities have dependencies on other libraries.
You can no longer create new activities of these same types.
