Slow response to button presses (Huion h950p)

I have Huion H950P, Linux Manjaro 5.15.12 I installed the drivers, put all the hot buttons in config.ini. However, at startup, when I press the button (on the tablet itself, it reacts quickly to the pen buttons), the program freezes for a minute (about 50 seconds) and then freezes, reacting to the hot button, while thinking, it does not react to the pen in any way. What could be causing this problem? I would be very grateful for your help :З
