@benvillalobos this looks like a normal version update, but it failed everywhere. Since you've been working with arcade recently, would you mind taking a look?

Looks like it's looking for dependencies from a different arcade version:

##[error].dotnet\sdk\6.0.100-preview.3.21202.5\Microsoft.Common.CurrentVersion.targets(4965,5): error MSB3030: (NETCORE_ENGINEERING_TELEMETRY=Build) Could not copy the file "D:\a\1\s\.dotnet\sdk\6.0.100-preview.2.21155.3\Microsoft.NETCoreSdk.BundledVersions.props" because it was not found.
is looking for 6.0.100-preview.2.21155.3, but the error comes from D:\a\1\s\.dotnet\sdk\6.0.100-preview.3.21202.5\Microsoft.Common.CurrentVersion.targets(4965,5) (notice the version numbers).

I think I know what's up. Update Versions.props to match DotNetCliVersion with the version in this PR's global.json

The ref assembly source change is legit and should be committed now I think. It should be stabilized by #6431 and thus only change again if the compiler does (again).
