Problem solved. Turns out it was some screen sharing settings that didn't automatically reset after unplugging a HDMI cable, and therefore the Mac was on some other setting that caused the problem.
ME TOOOOOOOOO HOW DID YOU FIX IT????
I know this is super old but I'm having the same issue. I've tried deleting the Options.ini file (and emptying my trash can) multiple times but nothings working. I'm on a Macbook Pro if that helps at all. if anybody has any suggestions they would be much appreciated but I'm not the best with computers so if you could make any instructions quite simple that would be REALLY helpful haha
@hbox36012 The first thing to try is to turn off Origin in-game: Hover over your username in Origin and select Application Settings to see the tab.
If you still can't launch the game, drag your entire TS4 game folder out of Documents and onto your desktop. When (if) it launches, a clean folder will spawn with no content. If you can start a new save in this folder—no need to spend time on it; this is just for testing—you can move the contents of your Saves and Tray folders from the old game folder to the new one.
I followed all the steps and I'm still just getting a tiny little window at the bottom of my screen during the main menu, thanks for your suggestions though
