Game not functional

Hello, I've never posted on the forum before but I'm hoping I'll get an answer. 

My game updated, I updated it yesterday, but now it is no longer functional. I opened it and on the main menu page it gave me the notification that my mods/cc had been turned off for the update. No big deal (aside from the fact one of my Sims on the preview is bald and shirtless). I turned them back on and loaded my game, but it was totally dysfunctional. I can't open cas without it sitting on the load screen and having to force quit the app, when I open bb the menus are a total mess, I can't open other households (when I click on them, the play option doesn't show up, but when I click empty households they still show the option to edit or make a family). Worst of all, my sim is still bald when I go back to the main menu. 

Also, as far as I was aware, the burglar update was supposed to be base game and I didn't need the new expansion for it, but the burglar setting isn't in my settings, and my pack settings aren't there. This has never happened with an update before and I haven't seen anyone else dealing with these issues. All the possible solutions I've found are for older versions of the game, or were made for if I still had Origin (which I obviously don't). 

This was a lot so if you've read this, thank you, any help is appreciated. I have over 800 hours in this game, but I'm not super tech savvy so I don't want to uninstall or push buttons and lose my progress or anything.
