DeckUser

I’m using BigBox on the Steam Deck (windows 11) and for some reason the B button is mapped to “Esc” on the Deck and I absolutely can’t change that. As a workaround I used Windows Powertoys to map ‘Esc’ to ‘O’. Confirmed the B button is now “O” using notepad. But now when I set controllerenable to “false” and keyboardback to “79” it does not work. Any idea why it would not work?
