Keyboard controls in the game r so messed up, the number of keys they have pre-binded and unable to rebind is insane on keyboard. Try resetting controls to defaults on both devices, I would hazard a guess the keyboard is the problem cause they binded something not in controls to something that conflicts with another player's controller. But in general test the game solo with only 1 controller plugged in at a time, see if they each work and ur buttons get rebinded properly. Then if u have another controller use that instead of the keyboard just to test if its the keyboard that's the problem. Short of that exit big picture mode, reset steam controller settings, restart steam, and repeat the steps.

I've tried these actions that you recommended to me, and I've noticed another one ♥♥♥♥♥♥♥♥ (taunt option doesn't working if I trying to change it too).
I'm turned off dualshock 4 support in steam controller settings, and returned to default options. Unfortunately, that not helped. A keyboard works in normal mode.

It could be possible strange, but also I've installed DS4 driver for dualshock 4. What do you think? Could be a problem with that app?

The DS4 Windows app tricks Windows into believing that your DS4 controller (dinput) is actually an Xbox controller (xinput). If you're adjusting Steam input settings for DS4 controllers, they probably won't work; instead, try changing Steam input settings for Xbox controllers, or try playing without the DS4 Windows app.

Additionally, analog triggers are treated as two separate inputs: a single axis joystick, and a binary button. You may need to adjust settings in the DS4 Windows app so that the button inputs triggers at an earlier point in axis rotation than what it is currently.

I haven't used DS4 Windows in over a decade, so some of what I'm saying may be old and not work anymore. But that's how I would've tried to solve this if it were me.
