Please don't quote ChatGPT answers, they sound very believable, but often have no basis in reality.

Material stress doesn't work like a soda can. Epitaxial thin films are stressed by an underlying lattice, for example, not by being squeezed in some container. These stresses can be very high (although i don't know the order of magnitude off the top of my head)

Imagine dropping your phone and instead of the screen cracking, the chassis blasts apart. Pressurising materials using other solids doesn’t disappear the energy needed to maintain the pressure.

Funny you mention glass cracking because tempered glass has the same kind of internal pressure. Safety glass on a car has nearly a kilobar. It breaks up without blasting apart.

Pressure != Energy. If it's a very stiff (aka brittle) material, then it doesn't deform enough to actually contain much energy even at high pressure.
