Android build failing with il2cpp.exe error

Hi guys, I'm trying to build an android application with il2cpp, but I am running into problems. I've tried a bunch of fixes and workarounds to no avail. (Such as this one https://forum.unity3d.com/threads/coding-inside-il2cpp-project.466391/)

I am using Windows 10 Home 64-Bit, I have both Visual Studio 2015 and 2017 installed, but with 2017 set as default for Unity, if that is any helpful.

Here's the error:

Spoiler: Error #1

Error building Player: 3 errors

The Editor.log file is attached.

Also, for me, this issue is reproducible on a clean Unity project, so it doesn't seem to be related to my project.

Just so you know, I simply reinstalled Unity from scratch, and that seems to have fixed the issue for me.
