[Bug]: playwright breaks to set content and load chromium with C# code

[DipakTated]

Version

1.40.0

Steps to reproduce

This is the code written in C#

using var playwright = await Playwright.CreateAsync().ConfigureAwait(false);

_logger.Information("Playwright starting to launch chromium");
// Open a new instance of the Google Chrome browser in headless mode
await using var browser = await playwright.Chromium.LaunchAsync(new BrowserTypeLaunchOptions { Headless = true }).ConfigureAwait(false);
_logger.Information("Playwright launched chromium");
const int SM_CXSCREEN = 0;
const int SM_CYSCREEN = 1;

// Get the screen resolution
int screenWidth = GetSystemMetrics(SM_CXSCREEN);
int screenHeight = GetSystemMetrics(SM_CYSCREEN);
// Create a new page in the browser
var page = await browser.NewPageAsync(new BrowserNewPageOptions
{
ViewportSize = new ViewportSize { Width = screenWidth, Height = screenHeight },
}).ConfigureAwait(false);

await page.SetContentAsync(result).ConfigureAwait(false);

Expected behavior

It should run without errors and load the html content

Actual behavior

while running this code, it throws this error sometimes and it happens once in 20 runs:

the script doesn't compile for me - do you mind sharing a minimal csharp project which surfaces this issue? Ideally a small git repository.

here is a sample csharp project.

I was not able to reproduce, I tried on Windows 11, maybe this makes a difference:

Also I installed the browsers via

 pwsh .\ConsoleApp1\bin\Debug\playwright.ps1 instal

Probably it doesn't help but I would try updating to latest Playwright - its usually a good practise.

as mentioned, this issue doesnot occur always but once in 20+ trials only. there seems to be problem at playwright transport layer according to me as mentioned in log files:

at System.Runtime.CompilerServices.TaskAwaiter.ValidateEnd(Task task)
at Microsoft.Playwright.Transport.Connection.d__40`1.MoveNext()

I see Page crashed which means the page is crashing. I recommend to set DEBUG=pw:browser env var which might give us more hints whats going on. Updating Playwright means using a newer Chromium which might has it fixed.

When is newer version v1.49.0 of Playwright going to launch, so we can start using from that?

~ 1 week - I recommend 1.48 so far.
