WinAppDriver: Random HTTP/1.1 500 Internal Error

@timotiusmargo, The RC2 works great! and is extremely quick comparing to previous releases.

Is there any updates? I get the same issue constantly. It launches the application but fails after. It launches successfully only if previous launches is failed so the instance of the is up and running( it can’t be disposed after failed run).
