Do you have any more information about the configuration this is on? CI doesn't seem to have seen this, at least naively:

It does appear on CI:

12:31:16.844 52323 Warming up the runner ...
12:31:23.218 52323 Test file:///warmup-does-not-exist crashed, we will now gather a crash log.

To be explicit, that logging is from https://build.webkit.org/#/builders/1235/builds/5202#bb-step-13 and then following the Full Logs link under the "layout-test" step to https://s3-us-west-2.amazonaws.com/archives.webkit.org/mac-sequoia-x86_64%20arm64-release-layout-test/[e-mail]
