In wpcf7_validate_email* not cannot be used wp_get_current_user()

I want to customize the validate email field to check if the email entered is the same as the login account. But wp_get_current_user() cannot be used to obtain user credentials.

// validate contact form 7

add_filter('wpcf7_validate_email*', 'custom_email_confirmation_validation_filter', 20, 2);
function custom_email_confirmation_validation_filter($result, $tag)
{
    $current_user_c = wp_get_current_user();
    var_dump($current_user_c);
    if ('apply-email' == $tag->name) {
        $apply_email = isset($_POST['apply-email']) ? trim($_POST['apply-email']) : '';
        $user_email = $current_user_c->user_email;

        if ($apply_email != $user_email) {
            $result->invalidate($tag, "間違ったメールアカウト");
        }
    }

    return $result;
}
