In qft there are no singularities, everything are fields. Particles are just such fields, a singularity in qft would mean you have a Dirac delta shaped field, I don't think such a field exists in reality and I don't think many working physicists would believe in them either. The big reason they can't even come up with math for the black hole singularities is just because the theory doesn't support working with such Dirac shaped fields. Edit: When they say electrons doesn't have a size, what they mean is that there is no limit to how small you can make an electron, not that it is always compressed into a point.
