Have you tried changing the polling rate in your Razer management software. Try changing it to 125 I’m blind someone recommended this already but whatever. Try a different mouse corded usb or Bluetooth usb I think it’s just a bad mouse usually what happens to me when the left click or right click starts going out like you mentioned this happened to my old m.o.u.s.e RAT9 I think loved that mouse but left click went out on it .
