Also, do you eventually run into the light of the dying star that made the black hole before crossing the horizon? Cause it would've never crossed the horizon from your outside pov I think, or does it??? So I guess you'd be vaporized by that radiation if that's what happens.

Everything that crosses the horizon remains on the horizon in the form of a still afterimage that becomes increasingly redshifted until becoming undetectable.

Some hypotheses suggest that hawking radiation could carry this information back out away from the horizon, but it's only a theory.

The light of the dying star has already long radiated away from the black hole. Once the star becomes a black hole, there's no way for all that light that already escaped to just become captured. See this video here to get a short visual explanation, by the same YouTuber.
