Segmentation Fault Error

I am trying to run the coupled WRF/WRF-Hydro model with the Crocus option enabled. i have completed upto ./real.exe process and generated threre three files wrfinput_d02,wrfinput_d01, wrfbdy_d01. But now I am encountering a segmentation fault (core dumped) error while executing ./wrf.exe. I have generated all the required WRF-Hydro input files using the WRF-Hydro GIS Preprocessor with geo_em.d02.nc. The files I createdinclude: fulldom_hires.nc, GEOGRID_LDASOUT_Spatial_Metadata.nc, GWBASINS.nc, GWBUCKPARM.nc, hydro2dtbl.nc, Route_Link.nc,soil_properties.nc
I placed all these files in the WRF run directory with the Domain folder. However, when I execute mpirun -np 1 ./wrf.exe i got the error
(ncl_env) sagar@sagar-OptiPlex-Tower-Plus-7010:~/data/coupled_wrfhydro_Copy/WRF/run$ mpirun -np 1 ./wrf.exe
starting wrf task 0 of 1

Please see the FAQ page for debugging suggestions
I have attached the error log files along with my namelist.input and hydro.namlist.
Could you please help me identify what might be causing this issue and what should be the namelist.input and hydro.namelist for two domains? I would greatly appreciate your guidance.

Hi, I notice a couple of issues that could be causing the segmentation error. The first is that I'm finding CFL errors in your rsl.error.0000 file. These errors indicate the model has become unstable. See Segmentation Faults and CFL Errors for additional information and potential solutions.

Additionally, for your domain sizes (especially domain 2), it's likely not possible to run with only a single processor. See Choosing an Appropriate Number of Processors for details.
