There is the ticket in community forum. https://github.community/t5/GitHub-Actions/Mac-OS-build-are-random-cancelled-no-I-do-not-have-fail-fast/td-p/54494
Customer reports that the post cache action on macos was failed randomly result in job cancellation. There is an example workflow run which met this issue: https://github.com/ankitects/anki/actions/runs/81024319
Restart the build process works fine.
Is there anything wrong in cache action?
