I've tried twisting two screw drivers into the slot but it doesn't seem to wanna rise up when pulling.

I've seen distributors with "long drive shafts" (i.e. extend from the distributor DOWN into the block and to the oil pump drive gear) made in one piece. It seemingly was a common JC Whitney thing back in the day "to reduce free play" (i.e. instead of leather pieces.)
I can't say I've ever seen a long shaft extending "up."
More than likely you got water somehow into the oil pump drive gear/housing. The "collar" at the top of the housing doubles as the "locator" for the oil pump drive gear tang. I'm imagining the two are rusted together.
Rust of course occupies 1-1/2 times the volume of the carbon steel it's formed of.

Note the "pin" holding the upper collar. Perhaps you can file/grind off the upset head and use a pin-punch to drive it through - releasing the collar to go up? Meh. Spring still in way.
