Can’t even play anymore, it’s so broken

I’m playing on PC. It doesn’t crash to the desktop, it crashes when I’m saving or kind of a slow crash where it’s just stuck in a loop like I mentioned. Like she’s doing a pottery class and it’s just the same movements over and over again and the clock has stopped adding time (so it’s live, but clock looks as if it’s paused). One time the phone didn’t have any options on it except the home one and all I could do was call the police but she was at home and there was no event happening or anything so I had to close the game, she couldn’t do anything else. I’ve also had several times where every sim and even npc is just stuck standing still doing nothing for hours and hours. Sometimes they eventually move but a lot of the time they don’t and I have to get out of the game. I know they’re not going to move when they’ve got both arms stretched out lengthwise (like a stick person) and they just stand there unmoving totally. It’s so weird. 

I also can’t play if I start out connected to the internet. If I am connected then once I load into my initial loading screen it’s darkened and I can’t click on anything. But if I’m disconnected from the internet I don’t have this problem.
