If you want to give a try its pretty simple.
Install BepInEx for Il2Cpp
You must be registered to see the links
Download UnityExplorer IL2CPP
You must be registered to see the links
Copy UniverseLib.IL2CPP.dll and UnityExplorer.BIE.IL2CPP.dll in to BepInEx\plugins
Run the game
On [Select a scene] select BathroomScene and click Load (Additive)
In Object Explorer find Enviroment and disable it (click the green box next to it)
And you're done
(Characters will spawn out of bounds tho cause their POI's are still the ones from the Bedroom scene but you can use Free Pose and drag them inside)
Video on how to install BepinEx even tho it is pretty self explanatory
