Description
Steps to reproduce
Upgrade Flutter to v3.38.0, then create and run a default Flutter project in VSCode/Cursor.
VSCode extensions veriosn
Flutter: 3.122.0
Dart: 3.122.0
Actual results
- After upgrading to Flutter 3.38.0, VSCode/Cursor cannot run debug mode on a real iPhone(iPhone Xr with iOS18.7.2); the application freezes after launch with blank screen (without displaying the local network permissions dialog box), but it runs normally in Android Studio.
- I tried
flutter cleanandflutter pub get, but they had no effect. - After using
flutter config --no-enable-lldb-debugging, it can start normally, However, it will launch Xcode.
Logs
After running, it remains in the "Flutter: Installing and launching..." state.
