@waneck I am not sure if I am doing it wrong or it is a bug. Because the sample platform game repo is outdated. Could you please shed some light on this?

I got something similar on Mac:

FGCObject and its descendants (including the offending type here ConstructorHelpers::FObjectFinder<UObject>) cannot be assigned with the = operator, because its move constructor caused its copy assignment operator be implicitly deleted. I think this is a bug in the glue code. @waneck
