There may not be a reason for GPS to not work at the poles... but I have seen GPS receivers that had hiccups at the equator and know of some that had problems at the poles... seems to be caused by math degenerating at 0 and 90 degrees.
The equator problem manifested itself as a reflection of latitude from negative latitude to positive latitude within a couple of km of the equator... this was before the days of well proven GPS simulators. It caused some problems starting King Neptune's court on time... https://en.wikipedia.org/wiki/Line-crossing_ceremony
I also know of a modern receiver that has problems crossing 90 degrees west (-90 degrees) longitude... It was a device developed in the far east and apparently never tested with a GPS simulator.
