public class {
    public async Task<
                (bool success,
            string content)> Func(
            ProductModel product,
            Settings settings)
    {
        req1.Headers.Add("Accept", "application/json, text/javascript, */*; q=0.01");
        req1.Headers.Add("Referer", $"{ShopBaseDomain}/shop/gd/dtl/goos.do?onlnGoosCd={goosCd}");
    }
}

Another form is:

public class A
{
    public (int x, int y
) C()
    {
        M("*/*");
        N();

seems like int in int y is misclassified. If we merge ) C() with previous line, it works. Also works if we remove first line (class declaration), or assign value of M like var x = M("*/*");.
