[ci-scan] Helix macOS reporter crash: ModuleNotFoundError No module named _cffi_backend

[github-actions]

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1420292
Build error leg or test failing: coreclr Pri1 Runtime Tests Run osx x64 checked - multiple work items

Error Details

Helix macOS agents have a broken Python environment causing the test result reporter script to crash with ModuleNotFoundError: No module named '_cffi_backend'. Tests themselves pass (exit code 100) but the work item reports exit code 1 because the reporter script fails.

This is a widespread Helix infrastructure issue affecting ALL pipelines that run on macOS Helix agents, including:

• runtime-coreclr outerloop (108)
• runtime-coreclr jitstress (109)
• runtime-coreclr r2r (120)
• runtime-coreclr crossgen2 (124)
• Multiple other stress/JIT pipelines
