I'm also having this issue, and it's very annoying.

We are having the same problem with our UI Tests. It happens about half the time lately and for the last few weeks. Common errors in the logs: Simulator device failed to launch... Failed to prepare device 'Clone 1 of iPhone 16' for impending launch. (Underlying Error: Unable to boot the Simulator. launchd failed to respond. (Underlying Error: Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding)) Test runner never began executing tests after launching Early unexpected exit, operation never finished bootstrapping - no restart will be attempted. (Underlying Error: Test crashed with signal kill before starting test execution.)
