The print didn’t finish because of a corrupt file apparently (that’s what the printer told me). I’m wondering what causes that big gap between the layers.

What are you printing in?
Are we looking down from the z axis?
What are your thermal settings? Hot end, bed, print cooling fan?
Anycubic water washable resin, shaken for 30 seconds before pouring in to the vat.
The leading edge of the ship (the edge pointing to the top of this picture) was hanging by supports off the build plate.
This is a resin printer so no hot end. 25 second exposure for the first 8 layers then 2.5 seconds each layer after.
I should have paid more attention, lol. In my defense, the top of the saucer looks like sloped top infil on layers.
In any case, I would have to wonder if there isn't some contamination that weaken that particular layer. While much lower than FDM, there are still internal forces that can build up and lead to cracking around weakened points. it could have just had some weirdness in the layer not sticking right acting as a focus for those stresses.
I'm guessing it's related to the corrupt file containing bad instructions, resulting in that layer having weaker-than-it-should adhession. the internal stresses then led to the crack happening (and expanding) as the print continued.
