OK, at least two things are going wrong here.

First, could you please send me the file that you have under 
"/System/Library/Fonts/Supplemental/Times New Roman.ttf"? I would like 
to understand what is going wrong with the N letter in this font. Better 
send it to me privately, as I suspect the list won't let it pass due to 
file size restrictions (or use a sharing service).

Second, Homebrew's way of packaging LilyPond seems to have missed a 
build change in 2.24, because LilyPond should not be using Times New 
Roman here in the first place, but its normal default text font C059. I 
have reported this at

https://github.com/Homebrew/homebrew-core/pull/118260#issuecomment-1368249969

Try using the official binaries while they fix this.

Best,
Jean
