An unexpected packet was received before the handshake. - Android Studio

Question

When I run the Flutter project on Android Studio, before running the application on the emulator, the event log displays "An unexpected packet was received before the handshake" for six to seven times. After that, the application runs properly on the emulator.
But when I run the same project on VS Code, it works fine.

Note: I also make Java applications on Android Studio and it never displayed this error.

Answer 2

If you're using Kotlin, make sure it's updated. It must be 1.5.31 or greater according to docs.flutter.dev. In android studio, go to Tools > Kotlin > Configure Kotlin Plugin Updates.
