Game is borked

I get this every time I sign into the game.  Not sure about when these issues have happened.  I have no mods in my game.  I built a house, finished decorating it, saved it to my library and then I could no longer load it into the game.  I ended up deleting it after hours of work.  Then I started a new house thinking it might just have been that one, but I raised the platform and nothing that should have raised with it raised, ie the columns etc.  So I had to delete it, also it made the game unstable couldn't even get out, had to use task manager to end the game.  I have every single pack, expansion, kit all of it, so not happy to spend so much on a game and then can't play it
