Hi Kieran,
it might not be exactly the same, but I encountered a similar error when deleting the hvp activities, some resources/activities didn't work. The reason was that the grade items of the deleted hvps were kept in the gradebook and therefore, it caused some error. Have you checked the gradebook?
