Can someone tell me how or why chess.com said I lost?

[Emekadavid2025]

This morning I was playing against an opponent on chess.com and was about to win, suddenly the computer alg said I had lost.
it was a huge surprise. So I downloaded the pgn of the game.
Since I am new here, first, I want to ask: can I upload the pgn file so others can go through it? Just the last two moves between us?
thanks

Sorry, I forgot to add. My pieces are white.

Your clock shows that your time has run out. Since Black has mating material, he wins.

Oh thanks. So I ran out of time! hah! When I was already celebrating the win.
Nice day sir.
