I downgraded my Windows 10 SDK version from 10.0.17763 to 10.0.17134 and it finally worked for me! It does seem to be a problem with the 10.0.17763 SDK somehow. Until or if we find out some better reason why this is happening, I guess this is an okay workaround for now, unless we continue to be broken in subsequent SDKs as well...
