Find Job "Build windows arm64 Release NativeAOT" with step "Send to Helix" which shows: https://dev.azure.com/dnceng/public/_build/results?buildId=1803448&view=logs&j=7bb91cf6-d57c-5393-cf5c-c884f1e50962&t=7729b4d4-9255-54d8-01fd-e831ebbb744b

From there, you can see "Sent Helix Job; see work items at https://helix.dot.net/api/jobs/7528557f-cbe9-4665-8fa3-6028facd5084/workitems?api-version=2019-06-17"

Which shows this:

Running these tests manually locally also results in this error.
