We don’t run builds since last year and we starting to do it again, but we didn’t change master and now always fails, not sure if we missing something but we always get this error:

Build continuing because “ContinueOnError” on the task “ResolvePackageDependencies” is set to “ErrorAndContinue”.
_HandlePackageFileConflicts:
Encountered conflict between ‘Reference:System.Data’ and ‘Reference:/Users/vagrant/.nuget/packages/netstandard.library/2.0.1/build/netstandard2.0/ref/System.Data.dll’. Could not determine winner because ‘Reference:System.Data’ does not exist.

Primary reference “System.Data”.

For SearchPath “{HintPathFromItem}”.

For SearchPath “{RawFileName}”.
Considered treating “System.Data” as a file name, but it didn’t exist.
There was a conflict between “System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089” and “System.Data”.

After this nothing works and we have 600+ errors, running the MSBuild locally all works just fine or doing Xamarin Archive (tested internally more than one computer) can someone help?
Best,
