TFLN rib waveguide - optical field results not showing

Hello everyone, I am trying to simulate the optical field of a rib waveguide in lithium niobate. I attached an image of the cross section, together with the mph file. I first defined a work plane and extruded it to create the structure. I defined the materials and inserted a diagonal refractive index for the lithium niobate since it is an asymmetrical material. In the end I defined the ports and inserted the mesh, and launched everything.
The problem is that the program runs and ends the simulation, without any shown error, but at the same time it doesn't compute the electrical field. In fact, the electrical field section under "Results" doesn't exist. Why is that?
