When I create a helloworld project it doesn’t compile, is ue5 so unreal? Can the engine developers fix problems like this first? I’ve never encountered this in any other area of programming, and I’d appreciate it if the engine developers would take this very low-level error seriously! Thank you, so that others can at least generate a helloworld program without any problems, thank you unreal ue5!
