Supervisor unhealthy, no entity loaded, add on issues

I’m having issue loading my HA since yesterday.

Context :
I’m using HAOS installed on a Rpi 4.

My HA crashed yesterday, at least the frontend. Couldn’t access it neither in homeassistant.local:8123 or via my public address.
Big issue big consequences : i hard rebooted the Rpi in the night.
After that, my frontend was available but i lost ALL my entities/integrations/addons even if all the needed files seems to be here (checked via FileEditor).

After a quick investigation, it seems i have an issue on the Supervisor loading tasks.

I searched everywhere i could, but this error is not really meaningful to me tbh.

And the worst here, i can’t restore any backup (even tho i don’t have a good/recent one) and my add-ons seem to be started but their icons are not loaded, it’s a weird behavior.

When i try to click on “Add-on Store”, i’m stuck in an infinite loading …

Any idea would be great…
