That error could happen if wp_is_application_passwords_available() returns a false, and the docs says:

By default, Application Passwords is available to all sites using SSL or to local environments. Use ‘wp_is_application_passwords_available’ to adjust its availability.

So, to enable the Application Passwords:

  • Enable SSL on your localhost,

  • Or define WP_ENVIRONMENT_TYPE either as a global system variable or constant, and set its value to local:

    // Example when defining it as a constant.
    define( 'WP_ENVIRONMENT_TYPE', 'local' );
  • Or use the wp_is_application_passwords_available hook like so:

    add_filter( 'wp_is_application_passwords_available', '__return_true' );
