Failure to collect hang dump from dotnet test running on arm64 MacOS in helix

[marcpopMSFT]

Description

The SDK is having timeouts in our arm64 test leg. To try to track this down, we've switched to using dotnet test with blame hang to collect hang dumps from helix. However, we've been unsuccessful getting dumps collected and saved to helix.

That invalid arg is a weird one for this one. Might mean the thread died here - there's no suspicious parameter otherwise.
