LUCI failure in unrelated iOS unit tests: `[FlutterPluginAppLifeCycleDelegateTest testCreate]`

PR: flutter/engine#19632
LUCI Build: https://ci.chromium.org/p/flutter/builders/try/Mac%20iOS%20Engine/7553

Failing tests:
	IosUnitTestsTests:
		-[FlutterPluginAppLifeCycleDelegateTest testCreate]

** TEST FAILED **

Looking at the engine dashboard, I also found a similar failure but it failed at a different spot: https://ci.chromium.org/p/flutter/builders/prod/Mac%20iOS%20Engine/6517

I retried here: https://ci.chromium.org/p/flutter/builders/try/Mac%20iOS%20Engine/7628 and waiting for the result it passed.

This is a test flake rather than infra flake, can somebody from the engine take a look?

This looks like a crash in the simulator framework itself.
