Segmentation fault on mdrun for two identical proteins

GROMACS version: 2023.1
GROMACS modification: No

Hi! I am trying to simulate two identical proteins in a box in GROMACS, but, upon attempting to perform the mdrun for energy minimization, I am met with a segmentation fault.

I am unsure if I made the system correctly, especially with respect to the topol.top or .gro files. Any help or guidance would be super appreciated!

The topol file seems normal.
Usually the incorrect equibrium step will lead to this error. Have you checked the trajectory or the energy change in the energy minization step?
