Very often when I run flutter drive for a test case in macrobenchmarks, with option --trace-startup (which is the case we run for devicelab. This issue is talking about running locally though.), the app crashes on the device with message "Unfortunately, macrobenchmarks has stopped." resulting in test fail. This only happens to Moto G4 but not Pixel 4.
The notice on host machine shows:

VMServiceFlutterDriver: Instance of '_WebSocketImpl' is closed with an unexpected code 1005
VMServiceFlutterDriver: Instance of '_WebSocketImpl' is closed with an unexpected code 1005

Any suggestion about what can check is appreciated!
