Error updating package, now won't uninstall or install

I tried to update the Terminus package, and it failed with an error. Restarted Atom, now Terminus shows no content under the Packages/Terminus page, although the Uninstall button is still showing. Clicking it doesn’t do anything, so I can’t uninstall or re-install.

It looks like it’s been removed, but Atom still thinks it’s installed. Any ideas what I can do to fully remove and re-install? Thanks
