Rod Version: v0.102.1

// Please make sure your code is minimal and standalone
func main() {
	path, _ := launcher.LookPath()
	launcher := launcher.New().Headless(false).UserDataDir(dataDir)

	u := launcher.Set("disable-features", "Translate").Bin(path).MustLaunch()
	b := rod.New().Trace(true).SlowMotion(200 * time.Millisecond).
		ControlURL(u).MustConnect().MustIncognito()

	page1 := stealth.MustPage(b)
	page1.MustSetExtraHeaders("Proxy-Header", "1", "b", "2")
	page1.MustNavigate("https://outlook.live.com/")
	page1.WaitLoad()
}

MustNavigate always return ERR_INVALID_ARGUMENT

I think it's because Chromium doesn't allow to set extra headers like Proxy-Header, Host, etc
