Comment 3 ayumi_kojima 2021-10-26 14:14:17 PDT 
I was able to reproduce the failure locally on Monterey arm64 using run-webkit-tests --force --iterations 50 --exit-after-n-failures 1 imported/w3c/web-platform-tests/resource-timing/status-codes-create-entry.html.

The test failed with r272882 and crashed with r272853 and older (Crash log is attached). No revisions available to test in between.
