This is saying that there's an error in the LoadScreen.gd file on line 50 (the only error involving code, repeated for every time it tries to report an error, from what I can tell)), while most of the rest of the log is complaining about missing textures and images.
Have you tried re-downloading it? I don't have what you're running it on, so I'm not sure if that's the cause.
