Home Assistant OS / Pi crashing

Hi,
so I have my Pi 4 8GB which is maybe half year old and it runs Home Assistant in Kinston 128GB ssd. Lately I have started to notice that HA has started to partially not function right. Most of my sensor goes to “unavailable”, supervision (add on do not work), history, logbook and automations stop working etc. My hue lamps and media control is still working trough ha.

Logbook


Do somebody have clue why this might happend and are there ways maybe to debug issue and prevent this happening? Powering off and on fixes the issue and this might happen few times a week maybe.
