I can't switch channels with hotkeys don't work at all

I can’t switch channels with my hotkeys at all, and before I could. I don’t know why this is happening and I’ve tried everything that I’ve read. I have my TS running as administrator, I’ve checked Self - Hotkey profile, I’ve checked my hotkey user.
The thing is that my PTT button is indeed working, but my hotkeys for switching channels are not. What can i do?
