I have a quite complex MAUI application that nicely deploys and runs on Mac Catalyst, Windows and Android. Despite I configured anything related to the bundle signing (and stuff like these) in the project's iOS settings, I keep on receiving this error on Application Output window while launching on iOS Simulator:
xcrun simctl launch --stdout=/dev/ttys000 --stderr=/dev/ttys003 --terminate-running-process 9301D251-1BD6-402B-BC92-563146ECD5BD com.improveforinnovation.semplice -monodevelop-port 10000 An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=3): Application launch for 'com.improveforinnovation.semplice' did not return a valid pid nor a launch error. No such process error HE0042: Could not launch the app 'com.improveforinnovation.semplice' on the device 'iOS 16.2 (20C52) - iPhone 14 Pro': simctl returned exit code 3
The application then immediately crashes.
I tried several suggested solutions, such as:
Still I can't figure it out how to get back to a normal deployment. Moreover, running a sample MAUI application (such as the one VS provides when you first start with MAUI), works perfectly on Simulator. The XCode (and CLT) version installed is 14.2 (14C18) and I'm attaching the information about the entire environment.

Is there any idea about the reason why I'm stuck with this error and on how to get out of it?
I was running into these same errors with our .net iOS application which we are working on moving over to net6.0-ios from xamarinios. Trying to run on the simulator on an M1 mac gave errors.
xcrun simctl launch --stdout=/dev/ttys001 --stderr=/dev/ttys002
--terminate-running-process 8CFC6FE4-MY-GUID-ABCDEFG com.mycompany.mobile -monodevelop-port 10000
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=3):
Application launch for 'com.mycompany.mobile' did not return a valid pid nor a launch error. No such process
and
error HE0042: Could not launch the app 'com.mycompany.mobile' on the device 'iOS 16.2 (20C52) - iPhone 14': simctl returned exit code 3
Somewhere along the way <RuntimeIdentifier>ios-arm64</RuntimeIdentifier> got added to my debug and release configurations in the iOS csproj file. I removed them and I can now run our app in the simulator.
