I am trying to replace a GFCI and a switch that share the same box, the old one had line and load opposite of the new and and I have now gotten lost.
I have 4 black wires 2 white and 1 ground, hot wire has the green tape and tested no other hot wires and I have paired off the other black and white wires with electrical tape.
I have the live wire connected to the common on the switch, no idea what to connect to what from here! Please help.
The breaker is off.

OK. So the zoom-in and brightening makes clear what is happening. Imagine there is a physical partition between left and right sides of the box.
On the left side
Goes the GFCI. Since you don't care about protecting any devices downline of here, this is super easy: Leave the "For Wizards Only" warning tape on the LOAD terminals, and everything goes to LINE. Almost all GFCI devices allow you to screw-to-clamp 2 wires under each screw.
On the right side
This is a simple 1-way (as the Brits call it) switch. 2 black wires and you're done.
You're welcome to use a 3-way switch, just make sure you put one of the wires on "common" (the black screw).
