Black Hole in M82
Two x-ray images of the central region of M82. left: The region around the black hole is glowing with x-ray radiation. right: Here the region is dim, indicating that the black hole has engulfed the matter surrounding it.

Therefore no, a large star could not collapse itself out of existence.
