Slack crashes on startup

[Owen]

Just ran an update and got an update to Slack desktop. Now whenever it starts it crashes out with

ssh: Could not resolve hostname slack-master: Name or service not known
rsync: did not see server greeting
rsync error: error starting client-server protocol (code 5) at main.c(1817) [Receiver=3.2.3]
FATAL[slack-getroles]: 'rsync --links --times -e ssh slack-master::slack/etc/roles.conf /var/cache/slack/_role_list' exited 5 at /usr/lib/slack/slack-getroles line 158.
FATAL[slack]: '/usr/lib/slack/slack-getroles' exited 5 at /usr/sbin/slack line 205.

The Snap version does exactly the same

The direct download from Slack's site runs fine
