Unreal Engine 5.4.4 cooked my blueprints. I make a brand new project and none of the start assets work, all of them have this macro node and shows an error. If I import the starter content, it does the same thing. Game runs in spectator mode at all times.
Man I have seen a lot of strange things happen in UE as well. Even doing something as relatively benign as renaming a folder making a whole project become unusable. Backup…backup…backup. But your situation may be an engine corruption. I don’t know what to tell you…try to repair I suppose and run the newest backup of your project.
Hey there @Hottestknees! Welcome to the community! As Clockwork mentioned, it’s possible an engine macro was corrupted. If you’re using the Epic Games Launcher, you can access it here.
