Re: can't stop my sim from apple bobbing and when pressing the arrow nothing happens

@SirPoet73  Depending on which graphics settings you change at the Main Menu, you may need to quit to desktop and launch the game again before trying to load a save.  Fullscreen/windowed switches should be fine, but maybe not the resolution.  (I'm not totally sure; it's been a while since I did this.)  Anyway, the best approach is to set all the graphics options the way you want them, quit, and reload.

If you still see crashes, try deleting your options.ini file.  You'll be back to default settings, but you can of course change them again, maybe this time with better results.

I doubt this issue has anything to do with Origin, but neither clearing its cache nor using it to run a game repair will hurt.  The repair process doesn't really do anything useful for in-game crashes.

How does a clean folder work for you, when you're trying to start a new save?  If a new save loads but your existing one doesn't anymore, that can be due to corruption in your old save, or it can be because of missing content.  That's why I asked if you had any installed mods/cc/worlds that the old save might need to load properly.  It's also possible that deactivating a pack can prevent a save from loading, but that's often hit or miss.  For example, any save that has seen Pets will almost certainly need that EP to be active in order to load, but removing Ambitions might not be an issue, unless you're playing in Twinbrook or have a sim that was in the middle of inventing or sculpting when you last saved.
