Hello there @RunBobFunStudios!

Checking through your log, there are naming convention errors present in the following lines:

error CS1514: { expected
error CS1002: ; expected
error CS1519: Invalid token ...
error CS1022: Type or namespace definition, or end-of-file expected

This means that the problem is due invalid characters in your project name, “hello neighbor prototype”, most likely the spaces included. UE tries to generate a target for hello neighbor prototype.Target.cs, then C# compilation fails due reading the invalid syntax.

The most clear solution here is to rename your project, to something like “HelloNeighborPrototype”, then clear the cache, via deleting the Intermediate and Binaries folders from your main directory. After that, re-generate your project files in VS, and launch/pack your project again. Hope this helps!
