I agree, you need a gear puller. You didn't have your crank puller screwed all the way in, make sure the center bolt is backed out all the way so the outside goes in all the way.

gear puller. you will only get two prongs on but it has worked in the past for me

use some WD40 or other lube or penetrating oil and spray the spindle

get tension on it and tighten slowly

sometimes a couple of whacks with a mallet is needed as well

make sure clean well and you grease the crank when you put it back on

good luck
