This compiled fine for me on lilypond 2.23.3, except for the warning about the empty ChordNames.
On lilypond 2.20 I got an error message similar to yours (without the filename weirdness), but it compiled fine if I commented out the ChordNames line or typed something into its music expression. I suppose you’ll eventually do either, as it looks out of place where it is now.
