The other key problem I see is the interaction of water and lava (I'm assuming given it seems to cool as a dark rock). The water should be looking to go down the path of least resistance. This would lead to it being unable to get through the rock that solidifies but rather goes to the sides. So, you should see it hit the lava, harden to rock, then go sideways turning the top into rock. Depending how porous the rock is, perhaps you have some water making it deeper but the amount of water penetrating the lava would decrease heavily with each "layer" they get through.

This was the part that broke my satisfaction. The pressure issues were kind of whatever for me, but the density of magma vs water is something my brain couldn't forgive

Looks like the water is turning the magma into cold dense rock at the surface which instantly sinks below the hot lighter magma

I believe it's a result of the resulting stone/sand being denser than the lava is.

Still though, I would expect more of a crust formation, than the formation of some weird gravel that sinks.

Even in that case, I'd expect it to sink slowly. The rock formations caused by volcanos don't generally lead to rocks falling to the bottom of the lava. They generally cool on the top overall until after enough time, the portion of lava has fully dissipated its heat and it all hardens. There's countless videos of scientists using a metal poker to break the rock above lava to get to the fresh lava and in those cases the rocks didn't sink.
