I ran into this with Char Elementalist today. relogged and tried 4 times.
I noticed when I tried talking to the friendly NPCs at the door that are not moving,
I see a glimpse of a minimized inventory window (determined by seeing my karma and cash flash quickly).
Not sure if that’s related, but in a dungeon our guild did once that bugged (progress stopped and we could not get anything to advance it), I saw that happening too.
I’ll try the suggested standing on the wall trick to interact with door….
door trick worked for me (jumped onto wall, stood above door, & interacted with it)
