sims 4 can't eat anything after i downloaded cats and dogs expandtion pack

I've had the exact same problem, I haven't tried playing another household yet though. I really don't want to remove my mods and cc as they are everywhere haha I will have no clothes or furniture in the house haha
It started with getting food out of the fridge and it just snapping onto the floor and sim refuses to pick it up to eat. So I drag it back in the fridge and so on, then it wouldn't let me read a book, from the bookcase, to the inventory, to the floor my sim wouldn't accept the action.
But now it's getting worse my male sim isn't doing anything I ask except "go here" action. He responds to that but anything else I click on doesn't even show up on the side bar as a task he is doing and also the little boxes that cause different emotions all flicker and disappear and come back and go silly. I'm quite annoyed as I have a baby to look after and she isn't getting fed and I can't use any cheats to fill her needs like I can with the adults. 
Also, I tried to garden earlier this afternoon before this happened and as soon as I planted seeds the whole game crashed and that's never happened before. I opened up the game and tried to garden again, and a further 2 times after that crashed every time I planted something. hmmm. 

I'm thinking I might have to remove all my mods and cc but I've been down that road before when I had a corrupt cc file and it well and truly stuffed everything up, and trying to get it all back together again was a nightmare, but my friends have not had that issue removing and reinstalling cc so I think that's just me. But anyway the other problems I was talking about is definitely in relation to the new update/expansion pack, and I also adopted 2 dogs not sure if that could have caused anything. Except, I saw two dogs I really wanted to adopt on the computer and I got one and the man came to my house and I paid the $200 but the second time I tried if after he left to get the other one it wouldn't let me adopt for $200 so I just shift clicked and pressed add to family and got the dog for free. I was kinda hoping that didn't make things worse but I should be able to adopt two dogs to start with anyway if I wanted to? Sooo :/ 

Not sure what the best way to fix this is -- pretty annoyed and upset as this is my favourite and longest standing family and in their dream home! ☹️ 

So I'm in the same boat and I saw a few other questions here with same sort of problem in the title. Glad I'm not the only one but also frustrating at the same time. Hopefully will be fixed soon with a new update or something? 🙂
