UI not loading after u/g to 0.117

Hi Guys,

I have tried to upgrade from 0.116.4 to 0.117.0 but seems to hang on starting Home Assistant.
Observer reports connected.

I left it alone for 10 hours while at work, still no UI and the only log entries are:

2020-10-29 12:22:15 WARNING (MainThread) [homeassistant.setup] Setup of zone is taking over 10 seconds.

2020-10-29 12:22:17 WARNING (MainThread) [homeassistant.setup] Setup of input_boolean is taking over 10 seconds.

I then tried a complete reboot and got a few steps further but then seems to hang again

I have SSH access and am currently trying a Supervisor Repair as any commands to ha core ended with

Error: Unknown error, see supervisor

…and that did nothing, still getting the Unknown error.

Any advice is warmly welcome.
I have a snapshot ready to go if that is the easiest option
