Re: [CURRENT ISSUE] Sims 4 Unable to Start, Game Data Missing or Damaged

This is my first forum post and please be kind to me as I've been recently having issues since the recent update, pre-ordering the latest expansion, and updating certain mods that I use such as MCC.
I have been getting this error message every time I try to start up my game and it crashes before it even reaches the main menu. 

I have tried uninstalling/reinstalling, removing mods, cleaning the files, and the whole other 9 yards of trying to fix this issue. NOTHING WORKED! Still kept getting the stupid error message after constant trial & error. Also how are you even supposed to use Origin if it's been inoperable & defunct since April of last year?

I just need help and answers because I enjoy this game very much!
Any helpful suggestion will be greatly appreciated!
