Hi Emma, I have the same problem with "copy course" in Moodle 4.1.9, I see that a backup is created first, with the restore I see this message "Potential coding error - existing temptables found when disposing database. Must be dropped!" and the course copy isn't created. But the message that the course is still busy with the copy doesn't dissapear anymore, very annoying. This error isn't always happening, sometimes the copy finishes, but it takes a long time to run.
