Can't make changes to build

I've had this bug for some time now and finally decided to report it because of how severe and disruptive it is. In my save, whenever I enable the cheat bb.moveobjects and try to place certain build elements like stairs, walls, or entire rooms, the build mode completely breaks. After doing this, I can no longer place or move things, and the game becomes unresponsive. Trying to exit the game leads to either an infinite loading screen or a white screen, and it even messes with my desktop tabs and windows to the point where I have to restart my entire PC to get things working again. What's strange is that placing small decorative objects or clutter with bb.moveobjects doesn't trigger this issue, and using stairs or rooms without the cheat works fine. Even after turning the cheat off again, the bug still persists once it has been triggered. I've done a fair amount of testing and can confirm this happens consistently, and I’m playing with no mods or custom content at all. I’m not sure if other players are experiencing this, but it’s made building in my save very tedious. Its very specific sooo idk :/.
