Updated to Creator 4.14 and 5.15.2 MSVC 2019 - now unable to generate main.moc

[luckachi]

I recently updated my Qt Creator to 4.14 and went from 5.14.2 MSVC2017 64bit to 5.15.2 MSVC2019 64 bit. My project had its command line arguments wiped out upon that update and now when I try to compile / run the app - I am receiving the following error:

error: dependent 'debug\main.moc' does not exist.

I have

#include "main.moc"

#include "main.moc"

To copy to clipboard, switch view to plain text mode 

on the last line of my main.cpp file

I have cleaned, ran qmake, built over and over again yet I can't seem to solve this issue (which did not happen while using MSVC2017) I use the Network Download example but have most of the code in a separate .cpp file versus having everything in my main.cpp. Nothing has changed in the code from using MSVC2017 and MSVC2019 so I am not quite sure why this would stop working?

Any assistance would be greatly appreciated.
