COMException (segmentation fault) when running HardwareCounters #2811
Description
Hello,
I am trying hardware counters for the first time after finding this article. I have unfortunately been unable to use these counters as I run into an exception when using them. I have stripped everything back to a tiny demo and still receive the error.
I'm on Windows 11 Pro.
My dotnet --version is 8.0.412.
$ dotnet run -c Release

Here is my program.
