title: Flutter app stuck on Installing and Launching step for physical iPhone
body: <p>Annoying problem here for my Flutter app: iOS13.3, Xcode11.3 on a physical iPhoneX. The iOS-Simulators all work. The problem is only happening on a physical device. The Flutter App freezes at startup (i.e. at Installing and Launching... step) ! Any ideas ??
  My flutter doctor -v does not bring any problems. Also tried flutter clean and flutter upgrade. But nothing seems to fix the problem...</p>
  
  <p>If I run the App from Xcode (Runner.xcworkspace) then everything works as well. Only from VSCode and Flutter, I can no longer launch my physical iPhoneX.</p>
  
  <p>Also, when uploaded to TestFlight, the App freezes at App Start ! (grey screen freeze). Therefore Apple App Store rejects all Flutter Apps for now ! Very annoying.</p>
  
  <p>I am not sure if the Installing and Launching... freeze is related to the TestFlight and App Store Problem !! Might as well be...</p>
