Windows Build failing "il2cpp.exe did not run properly" 2019.4.23

I am trying to run a test build and I've been unable to. I am getting these errors:

Spoiler: Output 1

I don't understand what I'm reading, and from googling it, most of the results relate to android, and the issue seems to vary. I've tried disabling firewall, rebooting my PC, upgrading to 2019.4.23f, running as admin, building to different drives / directories, moving project to a different drive / directory.

It seems to be isolated to this project as I am able to build other projects. I am using URP and Package manager packages only.

 

Not sure if related but I'm also getting this warning in the editor:

Spoiler: Warning

Visual Studio Tools: Unable to use UDP port 56590 for VS/Unity messaging. You should check if another process is already bound to this port or if your firewall settings are compatible.

I tried creating port exceptions in the firewall for port 56590

 

Someone on reddit helped me. Need Visual Studio, Windows 10 SDK to be installed. No idea why it wasn't anymore.
