sims can't interact with anything

I haven't played the game for months because i take more time trying to fix the game than i do playing it but I wanted to play again so i freshly downloaded it and it doesn't work I tested the game with no mods and started a new save file and my sims still can't talk to each other or interact with items i can only move them around but for example if i click on the computer and make my sims write jokes it shows that the sim is doing it in the queue and the level bar is on top of their head but the sims is not actually doing anything they just stand still. or i could be able to make them talk for a second and then it stops working again i also can't save my house to the gallery or my library i had to rebuild my house twice 😑
