The king is trapped on the open e-file, whites knight on e5 is preventing your king moving away from that open file. White will look to play Re1 in the next few moves after taking that hanging pawn on d4. Your queen is then in danger if white moves Nc6 leaving king in check.

The analysis will have given you what stockfish thought was the best move. What was that best move?
The computer calls 14...Rxf8 a "blunder" because it evaluated a different move (14...Kxf8) approximately 2 "pawns" higher. And 14...kxf8 is a better move, since it gets your king off the dangerous open e-file. But 14...Rxf8 is not what humans would call a blunder. Your position certainly doesn't collapse after your move
The eval of the position at 14. Bxf8 is at about -.38. After 14... Rxf8 the eval switches to +1.36, a massive swing.
Why? Black is up material, which is why at 14. Bxf8 the engine favors you. The other key difference in the position is K safety. White castled, black hasn't. Finally you're a few moves behind in development.
14... Rxf8 has the intention of preserving castling rights, but it keeps your K in the center. The engine thinks this is too greedy, and you needed Kxf8 with the idea of stepping off the open E file. This is the price for ignoring development for so long in your opening! With the K on e8 and the E file open, black has to play precisely to survive.
The line that you gave beginning with 14... Rxf8 15. Nxd4 features black surviving only by giving a piece back, something pretty difficult to find. Compare a line after 14...Kxf8:
Here's a sample line that the computer found that's pretty reasonable. The K stays safe on f8, and black has found a way to trade queens. Black has a sizable advantage here. The computer gives about -.80

The engine is kind of nuts on what it considers a blunder, where I would call that move an inaccuracy (at worst).
I've seen people give up chances to defend checkmate, and the engine calls it a mistake...
