I’m encountering an issue where the simulator breaks (e.g. cannot launch any new process) whenever any individual test fails during runtime. In my case the system successfully boots and runs tests, but the moment a test failure occurs, I see some 'Mach error -308 - (ipc/mig) server died' in logs related to sim clone, indicating the root cause preventing test retries from functioning - since the test runner itself dies and cannot be relaunched, there's no process remaining to attempt retries

Note that simulator boots, but after first test failure launchd unable to launch anything on same clone - logs contains plenty of "Mach error -308 - (ipc/mig) server died" errors (e.g. test retries broken at all)

Note that simulator at least boots, but after any first test failure on clone - logs has plenty of "Mach error -308 - (ipc/mig) server died" errors (e.g. test retries on failure doesn't working even on latest beta)
