/execute in minecraft:overworld run tp @s 11043.32 -51.73 1491.06 -1665.17 21.19

The cause

From @unknown in MC-216837.

The new caves, the noise caves, dont generate cave air. They generate normal air. The lava that generates under y -53, only generates in place of cave air. This means that lava can generate weirdly if normal caves intersect with the noise caves low in the world.
