I have similar, but not quite so severe, issues here.

Length of wire connected to the fried GFCI is resonant at or near your
operating frequency.
Others aren't so "lucky".

Dunno. Others here?

Yes.
I had an issue here on 40 meters with GFCI and AFCIs in our home.
The GFCI issue was solved when a 33' length (1/4 wave-length at 40 meters) of
electrical
panel "ground" wire (which was "grounded" to a city PLASTIC water supply pipe
(!!!) ), was
removed, shortened, then rerouted to a set of 3 ea 8' interconnected ground
rods driven into
the earth within 10 feet of our electrical panel.
YMMV.
