Could not build the application for the simulator.
Error launching application on iPhone 13.

I have already tried:

sudo xcode-select -r

also tried restart the Android Studio and emulator. also tried:

  rm ios/Flutter/Flutter.podspec  
  flutter clean

I was wonder why did this happen? what should I do to fix it?
