As you can see, the "Device Enabled (143)" field is equal to 0. I try to enable: Running in
xinput set-prop 10 "Device Enabled" 1
parallel:
xinput --watch-props 10
I get the following output:

As you can see, the device turns on, for some reason some properties change, after which it turns off.
Package installed xserver-xorg-input-libinput.
xserver-xorg-input-evdevand xserver-xorg-input-synapticsremoved. I don't understand what's the matter. I am not that experienced Linux user. I hope for your help.
