Xamarin Forms 4.3 Windows 10 Appx Package Error "mspdbcmf.exe" exited with code 1106.

I'm getting the following error on our build server:

       [Non FASTLINK] The input PDB file was not generated by the linker with /DEBUG:fastlink.

I have no idea what's going on or how to troubleshoot this. Any suggestions or info?

Using Visual Studio 16.4.1. I am able to generate the package on my local workstation.
