[ci-scan] Hang: System.Security.Cryptography.Xml.Tests.EncryptedXmlTests.DeepNonRootDecryptedXml_Throws #136624
Description
Build Information
Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1653598
Build error leg or test failing: net11.0-windows-Debug-x86-coreclr_checked-Windows.10.Amd64.Open - System.Security.Cryptography.Xml.Tests.EncryptedXmlTests.DeepNonRootDecryptedXml_Throws
Pull request: #136615
The remote child process exceeds its 60,000 ms timeout on Windows x86 Checked CoreCLR. Its accumulated CPU time is 28.8125 seconds; no failed depth-limit assertion is reported.
The same timeout is tracked in #136061, which has neither the Known Build Error label nor a Build Analysis signature. The test-depth reduction in #136200 was merged only into release/8.0; this occurrence is on main.
