Good job. You will be an expert on LTSpice soon.
1) you should get 150 to 160 volts from the power line. (one diode or four) I though the LTC7138 could only take 140 voltage. The spice model will not burn out like a real part.
2) with only one diode the value of C2 must be much much bigger.
3) some plugs are wired backwards.
With the external MOSFET the circuit can handle 110 or 220vac/dc with out any changes. MOSFET and Diode are the limiting factor for current and voltage.
