Ionic vue iOS app showing blank screen on Capacitor v3

I could not able to load the iOS app on the iOS emulator or device using the development server, tried almost all the possibilities and the following commands
ionic capacitor run ios -l --external

ionic capacitor run ios -l 

For android ionic capacitor development server loading and working perfectly fine for both emulator and device but for iOS, it is returning the blank screen and the app is not loading.

I can executeionic cap build ios from VScode and it build the production in xcode and run successfully for device and emulator, but it is really frustrating and time-consuming to do this practice from VScode to Xcode.

Following are the system configuration , please advice

Ionic Framework : @ionic/vue 5.5.2
