wrf.exe - Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

The programs geogrid, ungrib, metgrid, and real have run successfully. I have used ERA5 single-level data and ERA5 model-level data (138 levels of data) and produced met_em files (note: instead of regular pressure-level data).
While running wrf.exe as mpirun -np 32 WRF-4.6.0-ARW/run/wrf.exe, I'm facing the following error as in the rsl.error.0009 file.
I have attached the required files below.

Please, can anyone help me in this regard? @William.Hatheway, @kwerner

Many Thanks
-Shravan.

Shravan,
Apologies for the long delay in response while our team tended to time-sensitive obligations. Thank you for your patience.

Are you still experiencing this issue? If so, can you check the met_em* files to make sure you aren't missing any data at any levels? Often when you get a segmentation fault right at the beginning, the issue is specific to the input data. If that doesn't seem to be the case, will you package all of your rsl* files into a single *.tar or zipped file and attach that?
 
Hi @kwerner,

Yes, I’m still facing the same issue. There isn’t any missing data in met_em files. I have tried for 2 domains, also 9 km -> 3 km, as the region is complex (in the Himalayan mountains), even though I am facing the issues. I've attached the rsl zip file (increased debug value in namelist), the met zip file, and the namelist file in Google Drive and am sharing the link here, as the file size is not supported here. Please have a look at it.

Hi @kwerner,

FYI, I accepted the Google Drive link long back. Could you please confirm whether you received the notification? If so, can you please help me with the problem that I'm facing?

Hope to hear from you soon.

Thanks and Kind regards
