My Razer Basilisk X HyperSpeed doesn't type keyboard letters

I use the buttons on the side when I play games but since yesterday they just don’t work with keyboard letters anymore. They work perfectly if I bind them to mouse actions, but if I bind them to any letter on the keyboard they just don’t work. I have no idea what could be causing this issue, before yesterday they were working fine and just overnight this happened. I alredy reinstalled synapse and even created a new account but it didn’t work
