Extension only works once after installing or re-installing

[yeswap]

Please paste the output of the following command here: sudo edit-chroot -all
chronos@localhost / $ sudo edit-chroot -all
name: xenial
encrypted: yes, locked
Unmounting /mnt/stateful_partition/crouton/chroots/xenial...

Please describe your issue:
ASUS Flip C100P running xenial encrypted with targets xfce,extension,xiwi

Crouton was working without an issue for over a year with no issues until CrOS77.

Now when I run sudo startxfce tries and fails to start the extension 10 times:

Error: not connected. Cannot connect to extension, retrying... Unable to start display, make sure the crouton extension is installed and enabled, and up to date. (download from https://goo.gl/OVQOEt)

I downloaded the latest Crouton installed and ran: sudo crouton -n xenial -u with no errors but it did not fix the issue.

I uninstalled and reinstalled the Crouton extension and it worked - once. The next time I tried to run Crouton it failed again until I reinstalled the extension again.

So now I have to reinstall the extension every time I want to run Crouton.

Anyone else seeing this or know how to fix it?
