OSMC hangs on boot at blue logo screen. Can SSH - possible to reinstall?

Had OSMC running on RPi for years. Suddenly today I booted it and it won’t get past the blue OSMC logo screen (just hangs there). I can SSH to it though, so I’m hoping there’ll be a way to reinstall OSMC from there but keep all my addons/library data etc. intact, rather than just formatting and re-writing the SD card??

Provide the output of grab-logs -A if you want support for the failure to start issue. Alternatively, grab the /home/osmc/.kodi directory and then restore it to a new installation.
