Minimun reproducible example

package main

	_ "github.com/mattn/go-sqlite3"
)

func main() {
	sql.Open("sqlite3", "db")
}

It looks like you installed Go via Homebrew. As per this, you may need to update CommandLineTools (i.e., XCode).

Thank you for the pointer. Indeed reinstalling command line tools did the trick.

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install
