我已经添加了超时或设置为零，但它不起作用，它只会永远加载，甚至在后端创建大量 chromium 实例，以 100% 消耗 CPU 使用率。

static async Task<Page> CreatePage()
        {
          
            var browser = await Puppeteer.LaunchAsync(new LaunchOptions
            {
                Headless = false,
                ExecutablePath = ChromiumPath()
            });

            var page = await browser.NewPageAsync();

            return page;
        }

public static async Task<string> Init(string vidurl)
        {
            string vidUrl = "";

            using (var page = await CreatePage())
            {
                using (page.Browser)
                {
                    await page.WaitForTimeoutAsync(60000);
                    await page.GoToAsync(serviceUrl);
                    var input = await page.QuerySelectorAsync("#link_url");
                    await input.TypeAsync(vidurl);
                    var donwloadBtn = await page.QuerySelectorAsync(".btn");
                    await donwloadBtn.ClickAsync();

                    await page.WaitForNavigationAsync(new NavigationOptions { Timeout = 60000 });
                   // await page.WaitForNavigationAsync(new NavigationOptions { Timeout = 0 });

                    var jsSelectAllAnchors = @"Array.from(document.querySelectorAll('a')).map(a => a.href);";
                    var urls = await page.EvaluateExpressionAsync<string[]>(jsSelectAllAnchors);
                    foreach (string url in urls)
                    {
                        if (url.Contains("tiktokcdn.com"))
                        {
                            vidUrl = url;
                            break;
                        }
                    }
                    page.Dispose();
                    await page.Browser.CloseAsync();
                }

                return vidUrl;
            }
        }
