Failed automated reset of MCU 'mcu'? ...?

Im getting, Failed automated reset of MCU ‘mcu’

No idea why. recently installed Klipper on my Artillery Sidewinder.

I tried setting to both Arduino & Command. With Arduino it fails but then I can hit restart in the dialogue and it will start up after that. With Command I have to power cycle.
[mcu]
restart_method: Arduino

Any help would be appreciated. klippy log attached.
