Hi,
I face the same issue is happening to me, started on iOS 18.4 beta 1 and is still present on the stable 18.4 release.
Issue is happening with both Xcode 16.2 and Xcode 16.3, on Xcode 16.2 I need to reboot my device to get the app unstuck in a launch state, on Xcode 16.3 I can just kill Xcode and the app will actually launch.
Lost connection to the debugger on “iPhone”.
Domain: IDEDebugSessionErrorDomain
Code: 22
Recovery Suggestion: Restore the connection to “iPhone” and run “MyTarget” again, or if “MyTarget” is still running, you can attach to it by selecting Debug > Attach to Process > Target.
Please collect and attach a [sysdiagnose](https://developer.apple.com/bug-reporting/profiles-and-logs/) from “iPhone” when reporting issues.
