Standalone job submission is getting failed

Hi there

I was trying to run a CSTEP job through the command line (not through the visualizer) but unfortunately, its getting failed each time with the following error:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
Can't open perl script "/mnt/data/materials_studio/MaterialsStudio20.1//etc/Gateway/root_default/dsd/servers/Castep.pl": Permission denied

The SLURM script I have used to submit the job is follows:

#!/bin/bash
#SBATCH --job-name=test
#SBATCH --partition=dev
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=40

module purge

MS_INSTALL_ROOT=/mnt/data/materials_studio/MaterialsStudio20.1/
export MS_INSTALL_ROOT
server=Castep
\\\$MS_INSTALL_ROOT/share/bin/runMSserver.sh \\\$server "\\\$@"
if [ \\\$? != 6 ]; then
exit \\\$?
fi
 
cat \\\$MS_INSTALL_ROOT/etc/CASTEP/bin/RunCASTEP.Readme

It would be highly appreciated if anyone can help me...?
