Segmentation fault - invalid memory reference when running ./real.exe

Using WRF 4.6.0 to perform regional climate simulations. However, I consistently encounter an error when running ./real.exe:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference. I set export MP_STACK_SIZE=200M and ulimit -s unlimited, but it is the same error here.
When I run the first case, there is no this message. When I run the second case, the message is here.

can you upload your namelist.input and namelist.wps.

Also any rsl.out and rsl.error files in a zip folder
 
While it is true that nesting is most probably needed unless inpuit data has already very fine grid, real.exe doesn't care about this. Something else is crashing it, I would guess too large number of cpu used for small domain or something like that. I don't see attached log files so can't tell much more that guess.
