I actually have this exact same problem - For me it starts every time I reconnect my keypad to my PC. I get analog input from the stick but none of the buttons actually give any input. In addition, Both the Azeron software and rewasd recognize that I am pushing buttons on my Cyborg. Rebooting my PC solves the problem, but I shouldn't need to reboot to plug a controller into my computer, it's 2023 already.
Very frustrating problem - Exacerbated by the usb end of my Cyborg being incredibly sensitive to even a slight bump (Same problem here with the classic too - I think the plug is just not tight enough to spec and loses connection very easily, as i've tried every usb port on this mobo+case, plus the mobo+case i had before this one).
