That naturally assumes the "VFD shutdown circuit" didn't fail and thus
kill itself off.

Once anti-snubbing circuits open from overuse then the magic comes out
of the box in the form of smoke.

I suppose the winding in the various motors take a blown Transistor

Of all the vfds I've replaced...only one could be found that was
caused by a shorted motor. Most VFDs (NOT ALL) have internal
protections that shut the VFD down if the motor fails.
