 > On an M! Mac I upgraded the CLTs and got the same error listed here.

 > I downloaded the current Xcode 16 CLTs from
 https://developer.apple.com/download/all/ and installed them and got the
 same error.
 >
 > I downloaded the new Xcode 16.1 beta CLTs from
 https://developer.apple.com/download/all/ and installed them and got the
 same error.

 > Then I blew out the CLTs with {{{ sudo rm -rf
 /Library/Developer/CommandLineTools}}} and installed the current CLTs
 (Xcode 16, not Xcode 16.1 beta) and then everything works fine.
