As you approach the event horizon, your frame of reference slows asymptotically to match that of the black hole. While the universe around you fast-forwards toward heat death, the Hawking radiation coming out at you blue shifts the closer you get until it is so bright as to be indistinguishable from a white hole.

You’d never cross the event horizon; you’d be disintegrated and blasted outward into the distant future as a part of that very Hawking radiation.

To an external observer, you likewise never cross the event horizon, but instead appear to slow to an ever more redshifted standstill until you evaporated along with the rest of the black hole. There are no contradictions between what they see and what you see.
