Given that white still has so much material on the board, it would be possible - albeit unlikely - for black to give a mate. For example, if your king moved to h8, the g-pawn promoted to a bishop at g8, the h-pawn moved to h7 and the rook moved out of the way, then it would be possible for black to give checkmate by moving the bishop onto the large diagonal. I guess this is just an unlucky situation where having too much material comes back to bite you, haha.
Because black can mate if white cooperates.
E.g. 60 Kh5 Kxf6 61 Kh6 Bc5 62 Kh7 Bf8 63 Kh8 Kg6 64 g4 Kh6 65 g5+ Kh5 66 g6 Kh6 67 g7 Kg6 68 g8=N Bg7#
E.g. 60 Kh5 Kxf6 61 Kh6 Bc5 62 Kh7 Bf8 63 Kh8 Kg6 64 g4 Kh6 65 g5+ Kh5 66 g6 Kh6 67 g7 Kg6 68 g8=N Bg7#
That would mean that K&B vs K&B of opposite colors is mating material for both sides. K&B vs K&N is mating material for the bishop side, and K&B vs any rook pawns is always mating material. That strikes me as patently ridiculous.
Have rules changed since I stopped playing in tournament chess? Is this another case where USCF and FIDE rules disagree?

K+B vs. K+N is mating material also for the Knight's side: White: Kh6, Ng6 Black: Kh8, Bg8 is mate.
K+B versus any pawn and K+N versus any pawn can mate as well. The any pawn can promote to a Knight and then help for a mate in the corner.
This is not as "ridiculous" as one might first think: there are real chess games where some combination leads to this kind of mate.
The solution is simple: play faster so that you do not lose on time and if you are too slow for that then at least take away his mating potential. E.g. 57 Rf5+ and 58 Rxc5 would have prevented a loss.
Other solution: play games with a slower time control.

Do you actually think you are being civil tpr? You seriously think it is constructive to critique moves made with less than 1 second on the clock that were obviously premoved? Do you think I care about the game result as opposed to wanting to understand the rule set used on lichess?
I am hardly a beginner. I have played 10s of thousands of bullet/speed games on here and ICC. I find it highly implausible that I never ran into a "you could self-mate yourself so opponent still has mating material" rule before now. Therefore I can only assume that lichess does this differently than ICC. That is why I asked if anyone knew if this was a difference in the FIDE and USCF(American) rules.

Would a remaining pawn make you feel better?
Yeah, USCF has some rule differences compared to FIDE. And some servers like lichess and playchess are close to FIDE, others are closer to USCF.
I like the logic and consistency of the FIDE rule in this respect, it needs less exceptions.

Yes Sarg0n, it would make me feel better because it would align with my understanding of the rules gleaned from 25 years of playing chess in the United States. Would you not be shocked as a CM suddenly finding you were wrong about an important rule?
Once IM Josh Friedel lost Rook vs. Knight in a big German Open otb on time. He was used to USCF where he couldn't lose but using FIDE rules he could.
48 Rxd6+ Kxd6 49 Rd8+ Kc5 50 Rxd4 Kxd4 51 Kxf5 would have allowed a simple win without risk of losing.
It is standard technique to first eliminate the mating potential.
