[MOD RELATED] Error code 102:457b7b46

Hello, I have been a gamer for 2 years with sims and I usually have issues with mods and I have started again redownloaded sooo many times. I have started a new game and I have played with these mods and tray files perfectly fine! Until yesterday my game just erased! I was confused. Luckily my households didn’t delete but my buildings were gone. I can access building and build things but when I want to play my household it goes back to worlds or when I play another household just to test it came up with the error code. I have researched for a whole day and I know it’s not my mods or tray folder because I was just playing with them. So this is out of the blue. It’s like I always have to restart the settings! I realised it was an issues when I would change my graphics to medium (I am playing on a MacBook Air as I always have) and since this issue started it was only letting me play my game if the settings were on low but I have played on high before??? It’s confusing. I have deleted cache files or the localthumb thing, options ini, I have repaired, restarted re-downloaded the game. I have literally done everything and it’s laughable. Please help me. Or do I have to delete everything and start again? But I know it’s not my mods…
