Sims 3 save quitting right before opening
Hi i think i may have ruined my save file but i am unsure.
im playing on an old imac desktop from late 2013 (running catalina, processor - 2.7 ghz, graphics - intel iris pro 1536 mb) and my game started crashing frequently whenever i played for more than 2 minutes so i thought to uninstall then reinstall every pack i have plus base game (i have pets, generations, supernatural, ambitions, late night and high end loft stuff pack).
but when i reinstalled, i did every pack but the pets one because i know it is infamous for being buggy. i then tried to reload my save without the pets pack but now i can't seem to get past the loading screen where you play that spot the item game.
i don't know where to go from here ive deleted every cache that you can, uninstalled and reinstalled about 5 times since this started and i can't get into my save file at all. i even tried getting into my backup file but it crashes at the same loading screen. i've even tried purging my ram before loading into the game but it still crashes at the same loading screen.
if anyone has any advice at all that would be great and highly appreciated. i would just like to be able to play this family again if that's even possible.
