operating-system: System completely hangs after upgrading from 11.5 to 12.0

Describe the issue you are experiencing

Followed this tutorial to initially install HAOS on TrueNAS scale as a VM.

Host :

• TrueNAS-SCALE-23.10.1.3

Symptoms :

• Console access (Spice) is unresponsive to keyboard.
• Serial Shell is responsive to keyboard, but any command I issue seems to hang.
• Web UI is loading some pages, but many are not loading properly.
• I get notifications on the bottom left that integration XYZ are loading, but it eventually goes to a more generic one that keeps coming.
• I tried installing 12.0 from scratch then restore my backup (partial or complete) with the same result after a bit.

Add-ons :

• Advanced SSH & Web Terminal
• Cloudflared
• Studio Code Server

Integrations (Other than default) :

• Cync Lights
• Dreame Vacuum
• Ecobee
• HACS
• Jandy iAqualink
• Orbit B-hyve
• Ring
• Roku
• Simplisafe
• SmartThings
• TP-Link Omada
• Tuya

Anything in the Supervisor logs that might be useful for us?

Can't really do that once upgraded, cause the system is unresponsive, including the VM console.
