Cannot Generate Project Files

Hey! I attempted to package my projected using Advanced Sessions/Advanced Steam Sessions. After a bit of searching I discovered that I needed to add a c++ file to my blueprint project in order to get it to work. So I did that and now my project won’t open in the editor and I can’t generate source files either.

Here is the current error I’m getting:
