Labrynith and scaling?
I am rather sure that the whole area is supposed to be a “group-event” area, thus it won’t scale for less than group.
Keep in mind however that you can still get the doors in the open world.

The doors in the open world did not seem to count at all. I closed 4-5 to check and none of them counted towards this achievement.
Everything scales except for the enemies placed around the map. A level 80 should be capable of soloing through the area and doing any regular door events.
For the achievement, you have to close doors by doing their event. In the open world, doors only have a chance of starting an event, whereas it’s guaranteed in the Labyrinth.

The open world doors need an event to spawn for it to count. I did most if not all 50 in Queensdale.
The open world doors that count for closing the door seem to be constant as far as I can tell. The doors that count are the ones were multiple enemies come out and count as an event. There are 4 in Queensdale that I have found, they have a slower rate of spawning than the other doors. Three out of the four I have been able to close solo if needed. The fourth can be pretty rough.
