THE SIMS 2 LEGACY CLOSING ALONE

Hi guys, I went back to TS2 Legacy these days and I noticed that my game closes by itself in the middle of my save which ends up making me lose my progress. Do you know what it could be and if there is any way to fix this? (I have it on Steam)

I only have the mods: Clean UI, default hairs, ACR MOD, and I downloaded an autosave mod yesterday, but it closed by itself before I could add any mods.

I've already tried removing all the mods but it still keeps closing. I believe it's a bug in the game itself.

I tried to search on Google, but it seems like no one really cares about the Legacy Collection.
