I recently ran into something similar with an older GE switch, tried all sorts of things to Reset it.
In the end it was simply a matter of putting the Hubitat Hub in Exclusion mode and a single Up press on the switch to get it excluded and ready for Inclusion/Pairing.
Does your Hubitat Hub confirm that it is Excluding a device when you run the Z-Wave exclusion process?
"Unknown Z-Wave device successfully excluded"
