Okay I am not sure what caused this issue but after doing the below changes I managed to get it working.
If you see the screenshots above, you will notice that I created “DemoApp” project inside “[Ionic] [Cordova] Projects” directory. So I thought may be the square brackets and space of this directory name broke something somewhere. (Still clueless about the actual cause)
So it worked after I renamed it to “IonicCordova” (i.e without brackets and spaces).
