Resolution Note:
After investigation I was able to confirm that the log4net error was actually a TypeLoadException under the hood which indicates that there are issues when static class initialization. I was able to fix the project by replacing the project's System dlls with ones from nuget: https://github.com/xoofx/UnityNuGet
