I've been stuck loading and can't quit

Try ctrl+alt+del open the task manager, then force close TS4.exe.

I understand, that you can't launch the game.
There can be two reasons for this.
First, you use mods and CC and after the last patch s, some mods are broken and you can't play the game because of it.
If yes -
If you have any mods move the mods folder to the desktop.
Delete localthumbcache.package file in the game folder - important!
Fix the game in Origin.
Origin/Library -right-click on TS4 - option "Repair game"
You have to wait until Origin will fix all packs, not only the base game.
Turn on the game to create a new, empty mods folder. Check if a game is working now without mods.
If it is fixed, copy from desktop your mods and CC and paste it in the new mods folder. First, paste script mods every time checking if the game is OK. Do the same with CC but if you have a lot of this, try the 50/50 method ( divide your CC into smaller batches for example 50 pieces in one subfolder and check these subfolders one by one) You need to find a culprit and either remove it or replace it with an updated version

The second reason maybe is your computer. (The computer does not meet the requirements of the game, failure Windows updates. Weak graphics card, outdated graphics card drivers, software failures.)

Have you tried to launch the game in windowed mode?

You need to use the  first method  described  in this guide
