The problem, as I see it here, is that you've got a switch that was switching the black leg but your sensor switch needs actual voltage to work which means it needs a supply black, a supply neutral and the switched black.

The red wire is used with a 3 way switch configuration or the 3rd leg for a fan/light. It may not be connected to anything. If it goes into the same wire sheath as the switched black, it's probably up in the ceiling with a wire nut on it.

I see whites in your box, tucked away. The white wire must go to that and not to the ground. When a GFI senses voltage on a ground leg it'll trip. Code also requires that grounds do not carry any voltages and now it does. That needs to change.
I didn't totally understand....but thanks I appreciate it I get "not right" though!

I tried putting the red / pink / purple (whatever color it is) to the white on the switch and it didn't work (wouldn't turn on or off).....does that mean anything?

No GFI's have tripped at all FWIW
