In a shipwreck at the bottom of the ocean containing air pockets, would you die from jumping in the water due to water pressure?

I’ve attached an image here, to further illustrate the scenario. Imagine that the wreck is at the bottom of the Marianas trench, 10km underwater.

Would jumping into the water kill you from the pressure? Or would it only kill you if you swam to where there is no cover on the right side of the wreckage?

No, you can’t put something above you to protect you from water pressure. It pushes in on you from all sides, including pushing upwards against the air bubble you’re in. Which means the air bubble must be pushing back just as hard. Which means the air bubble is already at that 10km depth pressure. Whether you’re crushed by the water or the air, it’s already happened. Sorry, you’re already dead.
