@EgorBo I may steal this one from you if you haven't started on it yet.
EgorBo commentedon Jul 19, 2022
Sure!

This no longer repros.

Yep, I can confirm that the last time this was showing up was few weeks back https://dev.azure.com/dnceng/public/_build/results?buildId=1859228&view=ms.vss-build-web.run-extensions-tab . Since then, I haven't seen these failures in Antigen.

See this failure on windows-x86 on latest Antigen run.
