How to start docker daemon in windows (using WSL 2)?

I installed Docker Desktop for Win10 Home. Everything went fine and I was able to start up minikube.
Later I decided to stop Vmmem.exe because I wanted to play a game.
Ran the following command:

wsl --shutdown

Now Vmmem.exe has stopped running but how do I restart it?

minikube start gives the following error

* minikube v1.22.0 on Microsoft Windows 10 Home Single Language 10.0.19041 Build 19041
* Using the docker driver based on existing profile

X Exiting due to PROVIDER_DOCKER_VERSION_EXIT_1: "docker version --format -" exit status 1: error during connect: In the default daemon configuration on Windows, the docker client must be run with elevated privileges to connect.: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version": open //./pipe/docker_engine: The system cannot find the file specified.
* Documentation:

wsl -l -v gives following

  NAME                   STATE           VERSION
* Ubuntu-20.04           Stopped         2
  docker-desktop-data    Stopped         2
  docker-desktop         Stopped         2

What am I missing here? Any help is much appreciated
