Getting errors of mismatched MVID

Building .NET Framework 4.7.2 projects using msbuild, and getting errors in many projects like the following:

CompilerServer: server failed - server rejected the request due to analyzer / generator issues 'analyzer assembly 'C:
  \Users\builduser\AppData\Local\Temp\.sonarqube\resources\2\System.Buffers.dll' has MVID '36e84b0d-9d74-4086-a062-54e

This is with the SQ .net scanner sonar-scanner-msbuild-5.3.1.36242-net46.

I can’t find any documentation on this error or what MVID is or why there might be mismatches. We are doing a 2-week trial of developer edition and want to make sure the assemblies are being properly scanned before we acquire a license. Just looking for pointers on where to begin analysis right now.

Thanks!
