CV Axle Removal Front Right Passenger Side?

Hello. So , my CV axle on my front right passenger needed replaced. I removed a very bolt necessary to get the CV axle. I removed the 12 point 30mm bolt holding the axle to the wheel hub. And i removed the bolt on the other end going into the engine oil pan. And the ring as well. The main issue i am having is , trying to remove the axle from the engine itself . It’s quite literally stuck. I’ve tried chisel and a hammer. I even ran to my local AutoZone and picked up a slide hammer. But yet, it will not budge. Is there something I'm missing that is holding this dang CV axle in? I’ve sprayed rust penetrating around where the ring sits . Any ideas? Please and thank you! Btw , its front right passenger CV axle is stuck in the engine.
