I don’t know if this explanation will help because words. Using the photo plane as reference:

Two tools, a flat head screw driver wider than the vertical gap where the hook is, and a needle nose pliers. The screwdriver is going to be used to try to rotate the hook to the bottom left to clear the horizontal metal band, while squeezing the two bars midway to help bring the hook tip past the horizontal bar

Duck tape? Could also try pinching the piece with needle nose pliers right at the bend.

It looks like it’s supposed to block it from going the other direction. So, maybe gently try to lift it over to the blocking tab?

Twist it so it goes around from the side instead of above? It managed to pass it before somehow to get to this position.

You could try to heat it a bit with a hair dryer or something, maybe that makes bending it a bit easier, I’m not sure. Just be careful to not heat up any surrounding chips too much.
