Just bought a new XBox controller "Microsoft Xbox Wireless Controller Electric Volt".

OK, It seems both issues were resolved by restarting ReWASD. Testing now.
Confirmed SOLVED with a ReWASD restart.

Also, how do I show that "Share" button on the ReWASD gamepad layout?

I updated my OP. Please read it again.

This is the "Share" button that appeared on Xbox series S/X controllers. reWASD can already remap it.

This new controller adds a new 3rd button to the face of the controller. Will you be providing an update so we can program this new button?
Added: I think there are other issues with this new controller. For years I used ReWASD with Steam games. I normally go into the Steam controller settings and remove all binds. This causes the game to ignore in-game gamepad settings and it allows the game (with the help of ReWASD) to treat my gamepad like a keyboard. I then use ReWASD to bind my KB keys to my controller. I have been doing this for years. When I do this with my new Xbox controller, It completely ignores my KB settings in ReWASD and no controls work at all.
