Game unplayable suddenly.

Hi:)

Since the past week, out of nowhere, my ts4 became unplayable as it would not load anything and was extremely laggy. I thought that my mods/cc became too much (no issues with them before)  so i slowly started deinstalling them. However, this did not work so i ended up removing everything but still the same issue persists. 

I have by now done every possible solution i have seen online and deleted my master save with months of work, my mods, changed game/laptop settings, updated drivers, deinstalled packs and everything but the game still is broken, the main issues being;

1. Game is incredibly clunky and laggy in both main menu, cas and active game
2. In cas, there is several interface components missing like for example i cant choose traits as that menu has disappeared
3. In the game itself, textures/sims do not load and the game is unplayable as no commands register for sims as well as the camera taking minutes to respond to my mouse movements

The worst part is that i have never had issues before, my game ran perfect with mods/cc and packs and the issues started out of nowhere, not even after a new update as i handled new patch conflicts. 

If you have any ideas on what could be wrong or clues, let me know please. I am DESPERATE.

Thank you:)
