Having the same issue on PC using the Epic Games client. Just updated to the latest nVidia drivers and tried a couple other suggestions I've seen elsewhere such as dismissing party members, lowering graphics details to minimum, and purging/replacing save game files. This is the only part of the game where I'm seeing this issue, but it looks like it's a gamebreaker if it prevents proceeding in the main questline.
This is happening as an instant CTD just past the room where Hiram is. I can exit the building the way I came in on the second floor, but not via the exit at the top of the structure.
Edit: Appears to be a similar bug described in this thread, but tweaking fullscreen/windowed didn't help in my case either.
Edit 2: It was interesting to see that this specific issue completing "Radio Free Monarch" was mentioned in the patch notes for version 1.1.1 here:
I ended up using the Epic game client to "Verify" the install. After it finished, it proceeded to download 19GB of data. Looks like the auto-update feature wasn't working right or some game data was corrupted. Looks like it's working now and I'm able to exit the building to complete the quest.
