I get the same error when HA loads, my model is SCK0A45

Seems to be ok after removing model from configuration.

I'm getting the same error all the time, even with the model removed from the config. The model I'm using is Air Purifier 3H.

Moved to external SSD and got the same for all 3 of my devices - Air Purifier 3 and 2 Air Humidifiers. I find some info that it can be power issue (+ 1A to SSD). Back to SD and all back good. Maybe you should check your power supply.
