Navigation failed because browser has disconnected!

[LeeeJoe]

Description

I try using puppeteer-sharp with Firefox and getting this exception after page is loaded: https://bot.sannysoft.com/. At that time, page https://google.com was loaded without exceptions.

Navigation failed because browser has disconnected! (Page failed to process Runtime.consoleAPICalled. Error reading string. Unexpected token: StartObject.

Complete minimal example reproducing the issue

            List<string> listArgs = new()
            {
                "--start-maximized"
            };

            List<string> listIgnoredDefaultArgs = new()
            {
                "--enable-automation"
            };

            LaunchOptions launchOptions = new()
            {
                Headless = false,
                SlowMo = 1,
                Product = isChrome ? Product.Chrome : Product.Firefox,
                Args = listArgs.ToArray(),
                IgnoredDefaultArgs = listIgnoredDefaultArgs.ToArray(),
            };

            browser = await Puppeteer.LaunchAsync(launchOptions);
            Page[] pages = await browser.PagesAsync();
            page = pages[0];
            page.DefaultTimeout = 5000;

            await page.DeleteCookieAsync();

            ScreenshotOptions screenshotOptions = new()
            {
                Type = ScreenshotType.Jpeg,
                Quality = 100,
                FullPage = false
            };

            Response response = null;
            try
            {
                response = await page.GoToAsync(siteUrl, WaitUntilNavigation.Load);              // Line of Exception #115
                Console.WriteLine($"URL: {response.Url}\nPage status: {response?.StatusText}");
                await page.ScreenshotAsync(Environment.CurrentDirectory + @"\Screenshot_01.jpg", screenshotOptions);
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}\n{ex?.StackTrace}\nPage status: {response?.StatusText}");
            }
            finally
            {
                await page.ScreenshotAsync(Environment.CurrentDirectory + @"\Screenshot_01.jpg", screenshotOptions);
            }

Thank you very much!
