lando setup fails on Windows if docker-users does not already exist

[AaronFeledy]

On a fresh Windows machine, running lando setup installs Docker Desktop and also checks for the docker-users user group. There seems to be a race condition here where the check for the user group can happen before Docker is installed. This causes the setup to crash with Could not determine group situation.

i can replicate this, did not see it previously because i only removed my user from docker-users and it is NOT removed by uninstalling docker desktop, you need to manually remove the group.
