driver.page_source throws 500 error after connecting to the app with "appTopLevelWindow" param

[bwomsm1]

I need to use the functionality which attaches to a valid Win app running process and window. I found that the flag appTopLevelWindow is not supported in the latest release of 1.2.1. But after installing https://github.com/microsoft/WinAppDriver/releases/tag/v1.2.99 I noticed that C:\Program Files (x86)\Windows Application Driver folder remains empty.

@anunay1 Can you please help with this issue?

@anunay1 I don't really care using version 1.2.1 its just that I need to attach to a valid running Win app process. I have the running app hex window handler but I am getting an error that the http request for attaching is not supported.

Can you please help with that?
