Razer Cynosa V2 Stops working

It was working perfectly fine until my volume keys suddenly stop responding but the rest of the keyboard was still working. I tried uninstalling the driver, and did a driver clean reset. When that happened all of a sudden the keyboard no longer responds to any inputs that I press. It still lights up perfectly fine, when plugged in it registers that it is plugged just fine, I checked device manager and see that it is functioning properly it says. Every key I press is a ripple effect, I even tried hard reseting the keyboard it still does not work after doing so, I uninstalled and reinstalled synapse multiple times, deleted profiles, and folders, and other razer apps, even synapse 3 and 4 does not work. I don’t know why this is happening, I even tried it on another PC and it still does not register any inputs, just lights up with ripple effects.

After trying again one more time, it suddenly started working again lol, i’m not sure why it wasn’t before.

Hello ItsDannyB,

Thank you for updating us about your Razer Cynosa V2 issue. It's great to hear that your keyboard started working again. It's possible that one of the troubleshooting steps you performed resolved the underlying issue. Sometimes, devices can behave unexpectedly due to minor software glitches or temporary connectivity issues.
