Well no danger of that. We certainly cannot do it on terrestrial scales. No way, no how. Not even with fusion and a collider ring wrapped around the equator. It still requires vastly higher energies.

Even if we could make a kugelblitz black hole right here, it would instantly fall out of reach through the Earth while barely interacting at all with any other particles. On the Planck scale, particles are mostly empty space. We wouldn't even get to study it.

The best way to build one is to surround a star with millions of orbital mirrors, then focus all the light onto a single point in space, with an accuracy of nanometers, if not picometers. Focusing enough energy on a single point will cause a tiny black hole to form. It's probably impossible to do by accident.
