Same issue here, explored the rooms before picking up the modulator and disabled the security terminal (left room). Also hopped up to the balcony. I don't know which of these actions broke the game, but exactly the same problem as the others described here, and posted by user Chny in another thread. I do have a save before picking up the modulator, so I can still leave the room and do other stuff - but still eventually a softlock here unless it gets fixed. And my previous backup save before that is like 10h ago ...
