Same exact issue here. Did some diligence, apparently this is all the way up to vergen itself.
Librespot - https://github.com/librespot-org/librespot/issues/1681
Vergen - https://github.com/rustyhorde/vergen/issues/478

Maybe issue is upstream.

Hi,
my instance of this problem was cargo trying to be helpful when reading two different versions

run:

cargo install spotify_player --locked --force

almost guaranteed to be an instant fix!
