Drip a lot of penetrating oil (Liquid Wrench or similar) on the threads and apply mild heat with a hair dryer. Repeat several times. A large adjustable wrench can be used to span the raised ridge and should allow more torque than the screwdriver you are in the process of ruining.

Replace the ball bearings when you finally do get it apart.

A bench vise works pretty good to.

Make sure u r turning in the correct direction. It's not always "righty-tighty, lefty-loosey".

Left handed threads on the drive side.

It is if you are removing the adjustable cup.

if you can get the adjustable cup off, leave the other one in, clean it a bit, and feel around with your finger on the fixed cup for pitting. if pitted, follow Sheldon "Unnngggggggghh!!!" Brown's advice. If not pitted, maneuver some grease into there, used caged bearings, and reassemble.
