"docker" command not working after homebrew cask install on M1 Mac

Question

I have installed docker using brew install homebrew/cask/docker and varying other ways yet when I enter docker --version to check CLI this error pops up

"-bash: /opt/homebrew/bin/docker: No such file or directory"

What should I be doing differently?

I have tried both installing through a .dmg file as well as through homebrew using cask.

You can remove the installation and run these commands:

rm -rf ~/Library/Group\ Containers/group.com.docker
rm -rf ~/Library/Containers/com.docker.docker
rm -rf ~/.docker

Then try to install docker again and it should work. The .docker directory must have been owned by the root user.
