Sims 4 Endless Loading Screen

Hey, so ever since the last update, my game is literally unplayable. I get these weird white screens and extreme lag. I also cannot load into the main menu without it taking forever. Once I get to the main menu selection to choose a household, I am still met with an endless loading screen.. my game has been like this for about a month.. I do NOT use any mods or cc. 

could someone please help me? i reallly would like to play my game again.
