I was able to resolve the issue by generating Visual Studio project files. I’m not sure why there would be a compiling issue if that’s all it took to fix things, but so it goes. Thanks to Kazuja on the reddit post for running through his steps with me:
Also thanks for starting to assist me here.
To resolve the issue, I opened the project folder within my UnrealProjects directory, rick-clicked on the .uproject, and clicked on “Generate Visual Studio project files”. After reopening my project in the editor and the solution in VS2017, the problem was fixed.
