Hello, I have been experiencing a (new to me) issue where several vital parts of Home Assistant stop working. Running for 3-4 years now with essentially no issues on a RPi4, now on USB flash drive.
My issue is this: I’ll notice that some automations have stopped working (not getting notifications for certain events that I would expect automations to be triggered by). I check my home assistant instance. First thing I notice is that in my Settings page, the usual update for the latest version of Home Assistant (most recent I saw was 2023.7.1) is no longer showing at the top of the settings page. This for me is a key indicator that something has gone wrong with HA. I then try and click the System Settings page button. I get a page that says “Error while loading page system.” Then pretty much every page on this settings page will return the same error, aside from the automations page which will load.
I notice as well at the same time that my Z-Wave Integration will not load. Going to the configuration page for z-wave also throws an error: “Error while loading page z-wave.”
Finally, and perhaps most importantly, I am unable to restart the system from inside the Home Assistant instance. I try to click the restart button, and nothing happens. I am unable to access any pages that might let me restart the hardware a different way as a result of these issues above that I have described.
So, in this case, I am far away from home for a while, with a malfunctioning home alert/management system, with no way to fix.
Anyone else ever run into this issue, or idea for steps to diagnose and repair? I’ve tried pulling logs, but they are so heavily verbose to the point where I’m not sure I could ever diagnose the issue. And, in the system’s current state, I cannot even access the place where logs are stored in the UI.
