Build failure on .NET Core SDK nightly builds

[filipnavara]

Steps to reproduce

I have a scripted pipeline (https://github.com/filipnavara/mono-performance/blob/master/azure-pipelines.yml) running dotnet/performance benchmarks every other day against multiple runtimes. The last successful build happened on 2019-11-06. The next build scheduled on 2019-11-08 failed early on (https://filipnavara.visualstudio.com/mono-performance/_build/results?buildId=222) with the following error:

MSBUILD : error MSB4017: The build stopped unexpectedly because of an unexpected logger failure.
Microsoft.Build.Exceptions.InternalLoggerException: The build stopped unexpectedly because of an unexpected logger failure.
