Hammer time! I had to do this too and it is all that worked. Tried lube, solvent, I have every size rare earth magnet and even a fine dental pick. It was wedged so a vacuum was useless. I had to use 2 extensions and weave it through wire bundles because it was almost directly below the frame. A few wraps with a hammer and it popped loose. You'll note that my shim also chipped. This happened before it got stuck, this was not due to me trying to pry it out.
