doesn't respond to input

Hi.

I've mapped my generic USB gamepad as a GC controller. It detected all the buttons fine.
But once I start the game, it stops responding to all input. None of my gamepad buttons do anything. It doesn't respond to the keyboard either. I can't pause or stop the emulation. I can't toggle fullscreen. Nothing. The game audio and video is running normally though.

Also neither the hotkey options, or controll config allow me to save any profiles. It doesn't let me type in a name.

What is going on please??
Thanks in advance.

Also, how do I map the analog stick? It's greyed out.

Does anybody have Dolphin working on Mac Catalina? Do the hotkeys work for you? USB controllers?
