ToucheScreen doesn't works inside Steam Client on SteamDeck (SteamOS)

Hi, we have a trouble with touchscreen; in desktop mode on Steamdeck, touch screen works fine, but when we reboot console in Steam Client, the touch screen doesn’t works. InputSystem don’t recieved any message from touchscreen. But there is a strange thing, when we use gamepad and after touchscreen, Inputsystem call OnChange and sees Scheme Touchscreen, after this nothing…
Somebody have a solution?
Thanks a lot for help!
