Sims 4 crashes when loading into household/starting new game

Howdy,

So my (or rather, my gf's issue) is that ever since the Discover University expansion has been released, she hasn't been able to play the game whatsoever.

What happens is that the game itself launches (although not without issues - if it's in full screen mode, it crashes immediately upon launch, but if changes within the options.ini file, the game launches fine) and the menu loads correctly, however, that is pretty much it.

If she wants to load her household - the game loads and eventually the FPS's drop down to ~2 and the game crashes

If she wants to load any other of her saves - the same happens

If she wants to start a new game - the same happens as soon as the Create-A-Sim menu loads

I have done pretty much everything I could, from repairing through her Origin and changing the in-game resolution, through checking the full screen, windowed full screen and windowed modes and ending at reinstalling the game, cleaning the registry keys and removing all save files, etc.

What is worth mentioning is that the Legacy (32 bit) version works totally fine and has no issues at all.

I am also attaching the DxDiag I did just now and FYI - the system is running on the 64 bit Windows 10.

Thank you in advance!
