Even when uninstalled Razer won't remove my Macro

I recently decided to set up my first macro and now I realize that the key bind I set it to I use a lot more than I thought I would, so I wanted to change it. But whenever I try to open my Synapse 3, it always says failed to start. I tried uninstalling, and reinstalling, but it still says the same thing. Even when razer is uninstalled from my computer, the macro still runs when I press the key. I was wondering if there was any way I could fix this as it is getting frustrating as to why it still won't work even after an uninstall and reinstall.
