After playing around with hyper, it suddenly stopped working. No terminal window is shown. Neither when I start the app, nor when I open a new window or tab.
I tried to reinstall hyper, and I also removed .hyper.js and .hyper_plugins from my home-folder, without success.
Strange behaviour, when I hit CMD+N a few times (to open new windows) and then right-click on the dock icon and click on "Show all windows", that's what it shows.

Tried both, stable and canary.
macOS 10.13.5
Are there any other files I have to delete?
Also having this issue. I've reset the ~/.hyper.js config file and reinstalled hyper..
This happened to me as well on windows. Removing my .hyper.js file resolved it. No weird plugins or anything.
This fixed it for me: https://github.com/zeit/hyper/issues/3082#issuecomment-426236075
