I turned off the mods, and now the game works. I can make a new sim in create-a-sim, I can get in build mode again. I don't know which mods it would be. I have so many. Though I have a feeling some need to be updated but not sure which ones yet. I also decided to delete steam off my computer and unlinked it from my ea account, restarted the computer and now that works like it should. I'm gonna turn the mods back on tomorrow sometime and see what happens.
