'Segmentation fault (core dumped)'. What should I do to fix this error?

I was going to do secondary structure analysis (of protein) by using 'gmx do_dssp' module (I use Gromacs package). 'Segmentation fault' occurred after I gave the command line - gmx do_dssp -f native.xtc -s md.tpr -map and I couldn’t get the outputs that were so important. What should I do to fix this error?

• My current ubuntu version is 20.04
• Gromacs is a package that used for running molecular dynamic simulations. In this package, all command lines begins with gmx. In this here gmx do_dssp .... is a command for which had to give me required information.
• Before, such an error didn't occurred with ubuntu 18.04 .
• All commands except for gmx do_dssp works well (Gromacs isn't broken installed). That is, the problem is only with this command.
