Error when running NEMO 4.2.1

Hi, I had the following mistake when I tried to run nemo-4.2.1. Is it related to compiling? What does “Permission denied” indicate? I did not see errors when installing xios.

terminate called after throwing an instance of ‘xios::CNetCdfException’
what(): Error when calling function: nc_create(fileName.c_str(), cMode, &ncId)
Permission denied
