Households disappearing, Game Crashing, No possibility to get into Live Mode

Hello! I updated my game today after not opening it for a while, and I noticed various problems. 

When I first opened the game, I was welcomed by an unusual homepage.

I tried enabling mods and getting into the game, but even after choosing an already existing game save, I found the map completely empty. Not only were my households missing, but also the default ones.

In an attempt to check if I could at least make new ones, I also noticed that the game kept closing (not terminating, just reducing itself into a Taskbar icon). 

I managed to get into the CAS mode, and while randomly generating attributes for the Sim, the attributes disappeared. It didn't really cause any further problems, though.

Once the Sim had its house and everything was set to start a new game, the game kept taking me to the Select a Map screen. I unabled the mods and closed the game, but nothing changed.

This is my first time reporting, and my English is terrible, so I apologize in advance if this sounds incomprehensible. I hope I've made myself clear. Thank you in advance !!
