D-pad (left) steamdeck

problem with d-pad (left) after the last update (not sure if this is the problem) rebooted Steam Dec and when loading the system sound of clamping to the left ..... in Steam OS everything works except to the left .... when the game starts it does not work not one of the cross buttons ... and when the level starts, the character stupidly goes to the left (like a sticky key), but mechanically the cross looks and is pressed perfectly as before. .. and eventually reset to factory settings ... the result is the button to the left does not work (in the menu) but sticks in the game .. what should I do?
