I’m no expert but I think we’re looking at parts of the vehicle which were outside the pressure hull. Those parts would not have been subjected to such extreme forces when the hull failed.
Most bits of a DSV are actually outside of the pressure hull, just look at the designs of Trieste or Limiting Factor. This is to maximize the space available to human passengers inside the relatively small (and very expensive to construct) hull.
