Check around if a local shop has the Stein crank extractor. It’s a tap that cuts new threads and works with a Stein extractor of the same thread. If you already biffed the crank out and it’s a goner… Yeah, some kind of cutting at the taper to relieve the hold on the spindle and then a new crank. That crank puller looks like the Amazon/ali express special that pulls the threads out. A park tool or Pedro’s will work better.

There’s another tool called, The Crank Saver. It will cut a new thread in the hole and comes with a puller to extract the crank. This is the last chance to pull it off so I would use a penetrine and heat it up.

And throw away that crank puller.
Easier to drill out enough of that crank axle than it will be to cut off the crank arm. Get a new drill bit than can handle hardened steel. Take the pedal off the ride side so it will lay flat while you are drilling. Go slow.

Was the outer part that threads into the crank arm all the way in before tightening the inner part/pusher? In your pic it’s already pushed through

Been there bro. Time for new crank arms. I screwed it up so badly my local shop had to use some weird machine designed for car repairs to get the damn thing off. It was embarrassing even though they pretended not to know that it was a massive screw up on my part.

I’d either drill out the crank, or cut it off. Probably cut the crank off at this point. The crank is shot either way now.
Gear puller (may damage rings), pickle fork (definitely damages rings), ball joint separator (likely damages rings).
