Hey ho,
i got the same problem too.
Start to plan a deed and after a short time mostly if i try to go to the 3D view it crashes and only the reset butten of my PC works.
I think that some things like an oven or a staircase could cause that problem but im not 100% sure.
Got 3 full crashes so far, all of them includes staircases in 3D view.
I got an error log too. But i dont think its helpfull. ErrorLog
Greetings
My PC settings:
Windows 10
