error occurred at 30 minutes of running wrf.exe segmetation fault

now I have encountered a new problem. When WPS and WRF real run successfully, the error in the figure repeatedly occurs when executing./wrf.1740912954575.png
Although I reduced time_step to 4dx, 3dx, etc., the same error still occurs. This error occurred at 30 minutes of running. Here are my rsl.error.0000 and namelist.input files.
I tried to run the program with fnl data and ERA5 data, but I had the same problem with./wrf.exe, all of which worked successfully.

I try to download the GFS data on the web site NCAR RDA Dataset d084001 to simulate but still received the same error, And I get the same error every time I run wrf.exe until 30 minutes (although I also modified time_step to try 4dx and 3dx). Attached below is my namelist.wps file.
I would appreciate your prompt reply.

I have a few concerns about your namelist options. Please modify as follows:

cu_physics = 1, 0, 0,
radt = 9, 9, 9
ra_lw_physics = 4, 4, 4,
ra_sw_physics = 4, 4, 4,
w_damping = 1,

Please rerun this case and let us know if you still have problems.
 
Your case is a triply nested case with resolutions of 9km, 3km, and 1km,. if the domain is located over large topography area, the high resolution run can easily crash due to numerical stability issue.

As a starting point, can you run this case over a single domain? Please start from WPS, i.e., rerun geogrid and metgrid ( you can skip ungrib). if the single domain case works, then we can move on to 2-domain nest case, then to the thiply nested case.
