Hassio freezing - how to troubleshooting

Hello
TOday was the 3rd event: HassIO freezing .
I use it on a laptop with Linux running the IO (core). No docker.
The screen shows it seems to be ok, but I even can’t ping the HA. Shut off physically and then turning on the laptop back. It re-stablish.

Any guess how can I troubleshoot it?

Please clarify what is freezing. Nothing is called HassIO. Do you mean Home Assistant, Supervisor, Home Assistant OS, or something else?

Again, there is nothing called HassIO in Home Assistant and shortening it to IO doesnt help. Are you referring to this installation method? If so you might want to move the topic as it doesn’t belong in home-assistant-os

Freezing means nothing respond. From the web interface I can’t turn on off anything. And yes, I am using the OS. No docker.
