Does anyone know how to fix this?

I can create sims, but I can’t play the game after. Everytime I attempt to play or pick a house, it takes me back to this with that error on my screen. I’ve already deleted many mods and custom content and still nothing. I even removed all the mods at some point (I believe) and it still shows this every time I try to play or click a household. I’ve been having trouble with my sims 4 lately, so I haven’t played in a while because of it. I made sure to update all the mods I had. Also, I had to rebuy all the add-ons again because they were all disappeared from my Sims 4 Manage add-ons for some reason and it said that I haven’t bought them??
