Synapse 4 broke keyboard and mouse after updating

Both my keyboard and my mouse’s RGB are flickering so badly that it's trying to give me a seizure when I unplug them both. Upgrading the software was a terrible decision and I wish I could revert because it broke my setup RGB and has made my keyboard and mouse’s inputs more glitchy than before to the point where my computer just does not accept my inputs. I was already having problems with my keyboard double pressing and not recognizing my inputs ever since I got the Blackwidow v3 but that too has gotten worse.
