Can't package game from unreal source

So I’m running my project on the 4.17 stable version of the ue4 source. Everything works fine and I’ve packaged so many times for testing. Then I come on a week later and everything explodes. It appears as if all of these errors are coming from the source code itself and I’m not exactly sure what happened. Here is the log:

ive included it in a txt file as it is a large amount of text

Thanks in advance!
