PerfView Unhandled exception, .Net Core profiling

Hello i simply tries to follow this instruction to gather some trace information on simply HelloWorld! application:

https://github.com/dotnet/coreclr/blob/master/Documentation/project-docs/linux-performance-tracing.md

I have successfully collected data (i think) because zip file is ready. But when i try to open it on Windows under PerfView (1.9) i stuck with following exception:
