Sims 3 keeps freezing randomly for a few seconds (help)

Game keeps freezing every 10 secs for 5-10 seconds. The game has worked perfectly fine on my pc before, and even on my old worse laptop. I have a 3060rtx pc and 48 gigs or ram. It can run far more complex stuff then sims 3. Im not sure why this new family I started broke the game. I’ve tried reset sim, turning down graphics, refresh rate. Nothing works. It’s not like it’s lagging, it’s just freezing randomly. Anyone know what to do?

There are two sims in the family and one cat which I made in cas

they are in a small made home I didn’t build in costa del sol. I have played in this world before in the same house with even more sims on a less powerful laptop. I have a gaming pc now.

its a new save 

im just confused due to it working fine on an old dying worse gaming laptop but my new powerful pc is having issues. And it wasn’t freezing until around the time I put a bird cage with a bird in the house on the porch.
