Issue with Home Assistant - Help appreciated

I am having some issues with Home Assistant this morning:

  1. File editor and Grocy tabs do not open (blank page);
  2. Google Drive Backup generates a notification " The add-on is having trouble making backups and needs attention. Please visit the add-on [status page] for details." → when clicked the same behavior has with the ones above.

All I can get from the logs is related to Grocy:

This error originated from a custom integration.

Usually a forced restart (unplugging RPi from power) solves this. Restarting in home assistant does not usually do anything (not even restarts).

Any idea of what the problem is?

Thank you in advance.

Have you checked your storage isn’t full?

Not even close: 14.9%.

You are not giving us much to work with. However I agree this sounds like a storage issue, which brings me to the idea that your hardware might be damaged (sd card corruption is more common than you might thing).

Before your continue, I’d recommend to take a backup of everything on the system as good as you can.

Beware that your previous backup might already be damaged. Think about a backup using another computer and your RPi sd card to copy files

What additional info do you need?
