[ci-scan] Test failure: SOS.UnitTests fails on Windows x64 DAC/cDAC legs in runtime-diagnostics #132073

Summary

The SOS.UnitTests suite fails in the runtime-diagnostics pipeline (definition 309) on the Windows x64 release DAC / cDAC legs. The Build / Test task reports Tests failed: ...\SOS.UnitTests_net10.0_x64.html and the build exits with code 1. The failure reproduces on the DAC_windows_x64_release, cDAC_windows_x64_release, cDAC_verify_windows_x64_release, and cDAC_fallback_windows_x64_release legs of the source build and persists into the follow-up build, so it is a stable, non-transient signature.

Build error leg or test failing: Build / Test — SOS.UnitTests (-methodfilter SOS*) on Windows x64 release DAC/cDAC legs.

Pipeline: runtime-diagnostics (definition 309), branch main.

Build information

• First build it occurred: 1545665
• Follow-up build still reproducing: 1546062

The specific failing SOS scenario is recorded in the SOS.UnitTests_net10.0_x64.html test-results artifact attached to each failing build; the console log only surfaces the aggregate XUnit failure.
