VSCode Android Emulator Restart: Error -32000

Question

When I Restart my debugging on VSCode, I get this output:

Error -32000 received from application: Service protocol could not handle or find a handler for the requested method.
Restarted application in 1,009ms.

Also Hot Reload is giving this error:

Hot reload received invalid response: {type: Sentinel, kind: Collected, valueAsString: <collected>}

My environment is:

Mac OS X 10.15 19A602

VSCode 1.40.1

Flutter v1.9.1+hotfix.6

'Android iOS Emulator' 1.3.0 which is VSCode extension

When I start after stopping, the debugging it works but thats not a solution because its longer than restart or hot reload features.

Solution

Try flutter clean. This should resolve this issue.
