Not a theoretical physicist but I believe the theorized mechanism involves virtual particles. They are pairs of particles that pop up everywhere in particle antiparticle pairs. Normally they recombine nearly instantly but at the event horizon it may be that one of the paired particles falls into the black hole and the other escapes.

The issue with reforming stars is the universe is expanding at an accelerating rate. Which means while there will still be particles they will be isolated and too far away to combine into stars.

Virtual particles are a bit of a misnomer, as they're actually mathematical constructs that arise from perturbation theory and used to resolve certain complexities in quantum mechanics. Said another way, theoreticians use them to help better estimate particle interactions like those between say two electrons.
