Summary

Multiple Helix work items fail on maccatalyst CoreCLR Release (both x64 and arm64) and tvos-arm64 CoreCLR Release. Work items crash without producing individual test results.

15 work item entries affected across 3 legs (7 unique work items):

• Microsoft.Extensions.DependencyInjection.ExternalContainers.Tests
• Microsoft.Extensions.Hosting.Unit.Tests
• System.Diagnostics.TraceSource.Config.Tests
• System.Reflection.Emit.ILGeneration.Tests
• System.Reflection.Emit.Tests
• System.Reflection.Metadata.Tests
• System.Security.Cryptography.Tests

Note: This issue uses timeline ErrorPattern matching because Helix console logs for this build expired. Once a fresh build reproduces this failure, update with specific error text from the Helix console log and set ExcludeConsoleLog to false.

This issue was filed with the assistance of GitHub Copilot.
