As @Astrotronic suggests, the error message you provided suggests that there is not enough disk space available on your computer to save the package. It is trying to save a file named “Hair_S_AfroFade.uexp” in the “C:/Users/Lenovo/Documents/Unreal Projects/GAdventure/Saved/Cooked/WindowsNoEditor/GAdventure/Content/MetaHumans/Emanuel/MaleHair/Hair” directory, but it is unable to do so because there is not enough space on the disk.
You can try freeing up some space on your hard drive by deleting unnecessary files or moving them to an external drive. Also, try to lower the size of your textures and models, and use the compression settings for your textures.
Also, you can try reducing the amount of data that your game is trying to save, by removing unnecessary assets and reducing the size of your levels or maps.
It’s also a good practice to periodically clean up your project files and remove any unnecessary files or assets that you’re no longer using. Keep in mind that Unreal Engine saves a lot of files when you cook your project, so you might have to free up some space on your hard drive to avoid this error in the future.
