Hi, I have got the same issue on my MacBook Air 2018 Retina when haptic feedback stopped working after Ventura update. Apple Support refuse to believe there is some bug in update however I found a video on Youtube when a guy suggested to heat up touchpad and let it cool down.
I just bought a heat gun, set on a maximum heat option, turned off Mac, started heating up touchpad for about 2 min - 2cm above continuously moving it and never let it stay on the same place.
After I turned on Mac it didn't work, then I let it cool down and its start working again. I don't know how this helped but it works.
But remember you take risk and responsibility on yourself doing this. Try to put Mac at least on a tiles, not carpet, wood or other flammable surfaces.
