Razer blackwidow 2019 problem with synapse 3

Hello. I have a problem with the razer blackwidow 2019 keyboard and the Synapse 3 program. Namely, the keyboard is on and generally works, but when I try to change the lighting in the keyboard, synapse does not respond, for example, trying to turn off the lighting in the synapse program, the status changes to off but the keyboard is still on. I also noticed that when connecting the keyboard to the USB, the keyboard connects without any problems, but after a few seconds the USB disconnection sound is heard but the keyboard is still working. I would also like to add that I have the razer deathadder v2 mouse and everything works as it should.
