After latest VS2017 Update, dotnet publish fails on this task GetDotNetHost

Works fine on private pool:
Microsoft (R) Build Engine version 15.4.8.50001 for .NET Core

Works fine on VSTS Hosted Agent with VS2017
Microsoft (R) Build Engine version 15.7.177.53362 for .NET Core

Doesn't work on Private pool:
Microsoft (R) Build Engine version 15.7.179.6572 for .NET Core

The command we run is:
dotnet publish --configuration $(BuildConfiguration) --output $(build.artifactstagingdirectory)

Fails with this error message:

Any idea on how to troubleshoot that?
