UnsupportedEventParserRuntimeException with v4.2

[kerams]

Hello, I've just updated from version 4.1 to 4.2 and I'm now seeing the exception above.

It's a .NET 6 project and I'm doing DotNetRuntimeStatsBuilder.Customize().WithThreadPoolStats().WithGcStats().StartCollecting().

Reverting back fixes the problem, but I am frankly not sure if all the metrics are really emitted since the project is in development and there is nothing scraping it yet.

Hey @kerams, thanks for the report- do you mind posting the stack trace?

@kerams this should be fixed in 4.2.1, please let me know if it's not.

All good, much obliged.
