Suddenly DDJ-SZ does not work normally

I USE DDJ-SZ

It worked very well until I updated RekordBox a few days ago

After updating RekordBox and firmware

There are also a number of hotkeys that can not be used in normal operation.

For example, turning the Browser Section zooms

i not ues Browser Section I can not choose a song.

All the buttons are lit when the power is turned on.

And the cue in the mixer window is not pressed
I can not hear the sound at all with my headphones.

Is there any way to initialize all keys?

Reinstalling the firmware
Reinstalling Drivers
Reinstalling the record box

I tried three things.
