Error on deploy: 'gh-pages' is already checked out

I followed the setup instructions to the letter. When I try to deploy I receive this error...

Hi, thanks for reporting.

ember-cli-deploy-git uses git worktrees, and you can only have one git worktree per branch. The error says that you already have one at C:/Users/Pete/dev/deploy-covid-azores, so it must be trying to make a new one somewhere else.

Did you customize worktreePath? If so, delete the one in deploy-covid-azores first, and use git worktree prune to make sure git knows its gone.
