You hear physicists talk of microscopic black holes, but the force that
keeps atoms apart is so much more powerful than gravity that such talk
is just fools playing with math they don’t understand.
Neutron stars are are collapsed forms of matter where gravity is
stronger
than the electro-magnetic fields holding the electrons away from each
other and the protons.
It is possible that there is some kind of (as yet non-understood) force
that prevent a black holes complete collapse into a point--erasing all
visible aspects other than mass, charge, and spin.
It is just that our understanding of physics does not include such a
force.
There are quite a lot of other forces and effects fighting against the collapse. These are often viewed as "pressure". Electron pressure prevents neutron stars from forming until you have at least 1.4 solar masses. Beyond that, there is the pressure from the strong force holding neutrons together, effects from the uncertainty principle, the Pauli exclusion principle, and various quark effects.
These are not beyond our current understanding, but some of these degenerate matter states have not been observed. We have /some/ data about the inside of neutron stars, but it is limited. AFAIK we have not seen anything that is definitely more collapsed than a neutron star, but definitely not a black hole - quark stars, strange stars, and the like are hypothetical for now.
But it is entirely plausible that there are other limits to compression that we don't as yet know about and that would prevent a singularity even for huge masses.
However, AFAIK (and my knowledge here is amateur) it does not make an observable difference if there is such a force or pressure preventing singularities. Once you have reached the point where the object is smaller than its Schwarzchild radius (ignoring angular momentum for simplicity) then no information can escape from the object to the outside universe. From outside the event horizon, you see the mass, charge and angular momentum - nothing else, regardless of what things are like inside the event horizon.
Finally note: An electron can be modeled in QCD as if it were a black
hole with the mass, charge, and spin of an electron. ...
