2018's were also on the recall, but that shouldn't be it if it was working !
Asking because the couple with your same issue have Non-US ECU bikes.
But again yours was working

Refresh/check the jump wire at kickstand connector
Just looking at other maybes now ?
If you can check battery volts with key on would be great
(Other thread said wasn’t getting voltage on either pin ) (Check for .7 - .8 volts with key on )
If no volt meter you can jump battery from car to test if its a low volts issue if that even comes into play.
