It seems this is related to upgrading to macOS Ventura, not to a specific version of Xcode.

The worst thing about the issue is that Apple knows about it but they aren't fixing it in Xcode 14.3. RC 2 came out and the issue is not fixed.
So we will have to wait at least for several months it seems, which is unfortunate.
I am really tired of relaunching my simulator on every second attempt to run the app.
Known Issues
Repeated Build & Run targeting iOS 16.1 and later simulator runtimes may sometimes result in a hung launch. (101990080)
Workaround: Reboot the simulator device and reattempt the launch.
