I'm not able to reproduce it locally. It doesn't seem related to fingerprinting.
The message comes from xunit orchestration. It looks like a race condition.

@mkhamoyan Can you please look into this one? It's quite low priority (if don't start happening more often, but it doesn't seem so far). The exception comes from ToolCommand https://github.com/dotnet/runtime/blob/main/src/mono/wasm/Wasm.Build.Tests/Common/ToolCommand.cs#L110
My theory is that the process output arrives in .NET after the waiting for process to finish (as thus the test finished). Something like unsubscribing the handlers after the wait might be enough.
