This problem did not start until after the update a few days ago.
Did you play in between Dec 4th and dec 17th ?
Did you change anything other than the game update ? Driver updates ?
Yes i played in between those dates. No other updates to my system besides the game update. All my drivers are up to date. Like i said, never had this problem till now, even with mods. I have no mods installed right now, so its not a conflict with them.
TBH, I have no clue what is causing this issue for some and not for others.
Could you check if it works if you switch back to 32 bit: http://sims4.crinrict.com/en/2015/11/64-bit-is-coming-to-windows-pc/
