It wont load past the title screen

I managed to fix the game:

After reinstalling didn't help with the issue, I tried removing the folder where the game saves are, and I've found what causes the problem.

I tried to remove folders one by one, each time I checked if the game would work. Here's what you should do:

Typically, you should have that folder in your documents if you haven't moved it.
C:\Users\[your name/your computer name]\Documents\Electronic Arts\The Sims 4

then go to the "saves" folder 

And move or delete older saves. As far as I checked, the 4 recent saves left work safely, it is possible that more of them can work, but I checked up to 4 only. If you have the saves where you have other families, etc., copy them and save them in other folder if you want.

Let me know if it worked for you. ❤️
