Your simulation doesn't include your power input source, presumably a
rectifier, based on your label.

Full-wave rectified, straight off AC line. +VRECT to -VDC

You didn't show the Vrect waveform. What pulls it down? A bridge
rectifier without some pulldown can't keep sloshing charge into/out of
the current limiting capacitor.

Replace Vrect with a floating AC supply and a bridge rectifier, and it
won't work.
