Overheating Issues, one day it overheated bad, car shut itself off, bit of white smoke?

Got this car back in November 2022, didn’t have any problems aside from replacing tires and an oil change; car had been sitting a few months. I was using it for work, a small 15-mile commute. One day it overheats, bad, car shuts itself off, bit of white smoke. So far, I’ve replaced thermostat, water pump, added new coolant, and given it a second oil change. It’s still overheating. A/C and heater weren’t working properly until I replaced the T-Stat and Filter. What could be the issue and how would I go about finding it?
