Terminal couldn't start

• I am on the latest Hyper.app version

• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: KDE neon 4.15

• The issue is reproducible in vanilla Hyper.app:

Issue

Hyper is taking more and more time to launch each time and today the terminal hasn't started at all

Start by reproducing the launch failure on Hyper.app 2.1.2 and inspect the supplied devtools output, especially the “Uncaught Error: Not ready” message. Compare startup with the listed plugins and with a vanilla installation; done means the terminal launches reliably and the triggering condition is identified.
