There is logic for xunit in Helix:

https://github.com/dotnet/arcade/tree/main/src/Microsoft.DotNet.Helix/Sdk/tools/xunit-reporter (looks deprecated? but winforms uses it currently https://github.com/dotnet/winforms/blob/9db17fd379a4b2f36f6ac274b4700fafd4713876/eng/helixpublish.proj#L23 ?)

Some stuff may need to be adjusted for xunit.v3.

If possible to run the exe directly and not using xunit.v3.runner.console, that may be best. See https://xunit.net/docs/getting-started/v3/cmdline#running-tests-with-xunitv3runnerconsole
