Failed to initialize connection to any devices after upgrading to v3.3.0 #1919
Description
Steps to reproduce:
Dart Code v3.3.0, Flutter Code v3.3.0
1. Pressing F5 in editor
2. Selecting 'Start pixel_2 mobile emulator' at the 'Select a device to use' menu.
Available options:
Start pixel_2 mobile emulator
Create Android Emulator
*Despite an adb debuggable device was connected, no other devices were shown in the list.
3. The following error messages were shown, depending on the AVD was already running or not:
If already running...
Cannot launch without an active device
Failed to launch pixel_2: emulator: ERROR: Running multiple emulators with the same AVD is an experimental feature. Please use -read-only flag to enable this feature.
If not running...
Launching pixel_2...
Android emulator launching
Waiting for pixel_2 to connect...
Android emulator launched
Failed to launch pixel_2: Error: Emulator didn't connect within 60 seconds
*Similar behavior was observed if 'Create Android Emulator' was selected in Step 2.
4. No messages were logged in 'DEBUG CONSOLE' of VS Code
The above issue was also observed under Dart Code v3.3.0, Flutter Code v3.2.0
The above issue was not observed under
Dart Code v3.2.1, Flutter Code v3.3.0 nor Dart Code v3.2.1, Flutter Code v3.2.0
and everything behaves normally.
Everything also works normally if using flutter commands manually in terminal, e.g. flutter devices or flutter run -d <deviceID>

Many thanks.
I'd love to use the new Flutter Outline feature.
