It’s so small at that point it begins to act a little like a white hole (Hawking radiation iirc?) and evaporates quickly. It’s surprisingly difficult for matter to cross an event horizon. Edit-actually having a small black hole would unlock some truly sci-fi sounding tech. Like the fastest interstellar travel, seemingly unlimited power, etc.
