After cranking my car the oil pressure gauge read 120 then the pressure suddenly dropped to 0 and the oil light came on. I just had oil changed and there is no obvious leakage. I checked oil level and the dip stick is hard to read but it doesn't seem to be low or too low.

You may have a faulty oil pressure switch.

I would get a mechanical gauge in there and compare the pressures to spec and to what the sensor was reading. If the sensor was reading inaccurate, check the circuit and replace the sensor if necessary.
