Can’t enter live mode with new build

I replaced the original build on the “bjergsen” Iot in windenberg with a lot I found from the gallery and put a family but when I try to go in live mode I am stuck on a infinite loading screen. There are no mods or cc in my game or in the build. I already repaired the game.

There is no infinite loading screen if I play before placing the build.  I can enter the build in manage worlds and edit the build. I can play with the family when I merge them with another household.  I do notice that when I try to replace the original build by playing with the household and going in build mode, the gallery is glitched and acts like I haven’t clicked anything . I’m not sure what is causing this.
