Townies aren't hooking up and reproducing on their own in sims 4

My sims were creating relationships and reproducing on their own but then I had to uninstall the game to update my computer in December.  Ever since I reinstalled the game I am having the same issue, my world is slowly becoming a ghost town.  I hope they fix this soon.

You need to reinstall the Mod you had installed for this. The Sims 4 do not do this on its own.

You can enable "Fill empty houses" in settings to avoid it being a ghost town.

Bruh, yesterday I got in contact with EA help and they didn't help for (insert the s word here). Yes, they tried to "help" me fix this problem by restarting my game and clearing cache, but I specifically told them it was the townies's code that was the issue since they weren't programmed to look for a lover, get married, and reproduce. The entire time I felt I was talking to a robot since this lady kept talking with the cliche generated concern lines like "I feel how frustrating this may be for you". When are they actually going to fix this problem? I'm pretty sure I'm not the only one that told them about this issue. It's been about like what, 6-7 years? I can't remember right now how long it's been. I waited this long for them to fix this since I thought people had already complained to them about it and apparently people were right, they don't listen to us. Now I'm here trying to be heard, but I'm just a nobody to even bother listening to my complaints. I just wish those with a greater voice (like the youtubers) to speak up for us since they have a greater chance to be heard than people like myself. I'm sorry if this rant was too long, just wanted to let ya know what happened yesterday and how I feel about us getting ignored again.

Even in the Sims 3 you had to use a Mod called Nraas for this. So on a console where you can not use Mods your only option is as I posted above.
