Segmentation fault running gmx mdrun to introduce a protein into a membrane

GROMACS version: 2019.3
GROMACS modification: No

Hello Gromacs users

I’m trying to introduce a protein into a membrane using the tutorial of g_membed but when I try to run this command

gmx mdrun -membed membed.dat -s membed.tpr -mn index.ndx -v -c confout.pdb

I obtain a segmentation fault error and I do not know what this means and how can I solve it
The error is this one:
starting mdrun ‘Martini system’
1000 steps, 2.0 ps.
step 0Segmentation fault

Does someone know what can I do?

Thank you in advanced.
