Thanks Dan I've rolled back to kernal 5.11.0-46-generic and shut-down/restart is re-established normally. I've updated the grub to save this as default for the time being.
I'm new to the way Linux distros release their updates/bug fixes. My system is fixed (stable) for now, but how will I know if a new kernal release will address the bug in future? Any advice?
