I just tested all the other outlets in that area and pretty much all in
the rest of the house as well, they all test OK with the two yellow
lights lighting up on the tester, All the light/fan switches in that
immediate area appear to be working fine as well.

Thanks,

David

Vacuums pull quite a lot of power. Since your tester tells you that you have
an open neutral, it means that the neutral connection has come loose in one
of the outlets, switches or lights that are daisy chained on that circuit.
The most likely location would be a back stabbed outlet or switch near the
one that's not working. Check all the outlets in the vicinity of the dead
outlet. It's possible, but not likely that it has anything to do with a
GFCI, as that location doesn't require GFCI protection
