Error while building/debugging, need help for debugging

[Janesh7]

Hi guys, I'm new here.

I want to contribute to nvda, I want to create a plugin or add on for an app for which the nvda doesn't work properly because of the custom, complex ui of the windows app.

In order to do that I wish to debug the nvda properly so I can see which python/windows apis r being called and debug it properly

I have gone through the env setup/debug documentation and followed all the steps .. the output was very verbose but all of em ended on successful note .. I was looking for a nvda.exe in dist but can't find it and other exe files either end or r running external code
Running runnvda.bat and attaching it in vs only shows the injection code and i can't enter it and it says external code again

Am I missing smth here?
Can someone guide me in detail how can I debug nvda such that I can see the api calls being made when I do smth in nvda. (Im aware of the log files and python console present in the app.. i just need these for details of windows/python apis being used in code)

Also, for the cmd, (I have followed the steps before in the readme)
scons source nvdaHelperDebugFlags=debugCRT -j8
im getting this error
