Hyper (Windows) hangs and becomes unkillable

• 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: Windows 10.0.17134 Home
• Hyper.app version: 2.1.1 (was happening also on 2.0.0)
• Link of a Gist with the contents of your .hyper.js: https://gist.github.com/CAFxX/29719b9b1ce74ba41c5103d4c2e70836
• Relevant information from devtools (CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere): N/A (process is not responding)
• The issue is reproducible in vanilla Hyper.app: Haven't tested.

Issue

Sometimes (randomly, I've seen it happen sometimes when using ssh) the hyper window freezes, the title bar changes to "Hyper (not responding)", a popup appears saying that the application is not responding and prompting "End process" or "Cancel" (both sort no effect).

Trying to kill the process from task manager fails with "Unable to terminate process / The operation could not be completed / Access is denied".

Trying to kill the process from Process Explorer (running as administrator) similarly yields "Error trying to terminate Hyper.exe: access is denied". Curiously Process Explorer flags the Hyper.exe process as "Suspended".

The only way I found so far to kill the process is by rebooting the system.

The only similar issue found so far is https://github.com/zeit/hyper/issues/3342 but in my case the Hyper process/window never recovers and can't be killed so I suppose the two issues are different.

No source file, test, or entry point is identified. Start by reproducing the hang on Windows 10 with Hyper 2.1.1, including during SSH use, and compare the behavior with issue 3342; done means the cause of the suspended, unkillable process is identified and the application no longer requires a system reboot.
