First you don’t need to remove the crank arm if you only need to remove the pedal. You can just unscrew the pedal spindle, counter clockwise on the drive side, clockwise on the other side.
If you actually need to remove the crank arm, either you’re using the tool incorrectly (look up a Park Tools video on YouTube), or the threads in the crank are damaged. Its somewhat common, they are fragile, fine pitch aluminum threads. I’d recommend bringing to a shop. Maybe they can chase the threads with a tap for you, otherwise you’ll need to buy a new crank arm anyways.

Have you got the right tool? There are different crank extractors. The one you need will have a piece on the end so it pushes against the axle – without that part it’s pushing against nothing and doesn’t work. You can also sometimes do it with something like a penny.
Be careful with those threads now too – I’d clean them out and carefully wind in the extractor so it has good purchase.

Try the other side, it should screw in clockwise and.by hand. Getting past that you’ll need another tool to remove the whole crank bracket.

You can’t use that tool on alloy pedal crank, only a press at bike shop will work.

Since the threads have been pulled out the crank extractor will no longer work and your going to need a pickle fork.
When this happened to me, I had to remove the bottom bracket itself by using a flathead screw driver and a hammer

It’s catching the edge of the crank. Put a nut in the hole that’s about the size of the spindle but doesn’t touch the crank. It will push against this instead.

One of these jobbies.
