DDJ-SZ MIDI BUG

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?

I tried three things.

Reinstalling the firmware
Reinstalling Drivers
Reinstalling the record box

DDJ-SZ MIDI setting is abnormal.
All of the basic MIDI settings are twisted
I can not use my equipment properly
A proper DDJ-SZ mapping file is required.
This causes the DDJ-SZ to operate abnormally.
I tried to do everything I could.
Reinstalling the program
Reinstalling the firmware
Initialization of the equipment
etc
