pluggable called too early for SMTP plugins

I’m getting a fatal error on my SMTP plugin, it says another plugin is calling wp_mail too early. This is just what I was told by ai.

       private static function require_pluggable_essentials() {
            if ( ! function_exists( 'wp_get_current_user' ) ) {
                require_once ABSPATH . 'wp-includes/pluggable.php';
            }
        }

private static function require_pluggable_essentials() {
    // No-op. WordPress core loads pluggable.php on its own.
    // This avoids forcing wp_mail() to be defined early.
}
