Key board only works with direct power cable

I have noticed that my Razer Blackwidow V3 Pro keyboard behaves in strange way and it stops me from using it properly.

When it is connected to PC via cable Everything is okay and the charge status shows 100% hovewer when I disconnect it and enable 2.4 wireless connection mode the charge status suddenly go to 0%, LED lights on keyboard start blinking more rapidly than usual when I’m typing something on it and when I’m not the LED lights just switch off. What’s more, when I’m typing I can notice that the connection keeps dropping and after a moment it goes back. The keyboard shows for a moment in Razer Synapse and than dissapear.
