Playwright for .NET discourages using xunit see here. Also the playwright.config file does only work for Node.js.

I'd recommend to set the DEBUG=pw:api env var to get more logs. Most likely your site is not reachable or hangs.

According to their documentation it should be possible. I see you are using StorageState maybe try StorageStatePath instead. Their example:

var context = await browser.NewContextAsync(new()
{
    StorageStatePath = "userCookies.json"
});

https://playwright.dev/dotnet/docs/auth

It's not clear from their documentation, and I never used this library before and could be wrong, but I believe StorageState expects the stringified JSON and not a file path. While StorageStatePath expects a file path / file name to the JSON and will read the file for you.
