Faces all looking the same is possibly because people are hesitant to post their AI images of IRL celebs etc. Stable diffusion is really good at creating that sort of thing
The room is filled with a deadly gas. Either it is built so that it vents into the room naturally from deep under ground, or a diffuser is periodically refilled by whoever controls access to the room.
The McGuffin is the antidote to the gas, which you must obtain and administer before entering.
One way of getting a very localised danger like this would be to put it near radioactive ore deposits? You can only go in with a lead shield, and have to angle it correctly
Depends on the context, like what world it is and where the room is located, and so on.
I suppose it's in a building that people have access to except for that one room, and that it's a world where, while not particularly sophisticated, explosives exist, so it should at least have very strong walls. If magic exists you might want to avoid using it for this purpose as it often becomes a "because" kind of explaination, but you can use it as a tool (e.g. an obstacle that can only be overcome with powerful magic, and the magicians who are capable of such power can be counted on one hand).
If magic is a no-go, maybe it simply requires a specific kind of key to open (but maybe it's too high tech for your world?)
Key?! What kind of futuristic sci-fi do you think I'm writing?!
But seriously speaking, I think I'll make it so that you have to visit a cave with a stream flowing through it, grab a fish from the stream, maybe do some rite and then the fish burps a key out.
Set up a monastery in the surrounding building whose religion is centered on only letting in the one person. The 'key' is a complex ritual (like happens nightly at the tower of london) with lots of phrases and movements to learn. The ceremony happens somewhere dangerous to the person requesting access.
