Razer blade keyboard not working

Recently my fn key has stopped working. When I press the key only the function keys light up as normal but they do not change the function of the keys. currently in Synapse my function keys are set to multimedia but the keys just do normal functions. custom key binds set in Synapse are also not working non of my custom key bindings function how they should. I have tried repairing synapse, reinstalling synapse, and rebooting serval times as well as uninstalling the keyboard in device manager. Not sure what else I can do I am on a razer blade 14 2021.
