The Attrition Backrooms

"If your not careful and noclip out of the map in certain areas, you'll end up in the Attrition Backrooms, where it's nothing but the musty smell of old wood, the overwhelming sight of yellow-brown, the endless background noise of spherical lamps at maximum hum-buzz, and approximately six quintillion square studs of randomly segmented maze-like rooms and hallways to be trapped in." Made in 2022, a while before all the backrooms content oversaturated the internet. It hasn't been updated in years so it may be broken.
