LZW31-SN responds to zwave but front led and load are off

I have this Red Series Dimmer from 2020 that suddenly went dark. All zwave functions work, can include, exclude, ping, factory reset, etc.

But the led bar is always off, and the light doesn't turn on.

Is it garbage, or can it be recovered somehow? I assume warranty expired on it...

If it needs replacement... not sure if i'd go with Inovelli again. Doesn't seem to reliable if it dies after 4 years...
