I'm encountering the error "Program received signal SIGSEGV: Segmentation fault - invalid memory reference." Could anyone help me resolve this issue?

Hello, I'm sorry to bother you. I have searched for my issue on the forum, but unfortunately, I haven't been able to resolve it.
My current system is Ubuntu 18.04, and I'm using CESM 2.2.0.

So far, I have only modified two files: ~/cesm2.0/cime/config/cesm/machines/config_compilers.xml and ~/cesm2.0/cime/config/cesm/machines/config_machines.xml. The specific contents of these files are provided in the attachments.

In the config_compilers.xml file, I added the following configuration:
<SLIBS><append MPILIB="mpich"> -lnetcdf -lnetcdff -lblas -llapack </append><append MPILIB="openmpi"> -lnetcdf -lnetcdff -lblas -llapack </append><append MPILIB="mpi-serial"> -lnetcdf -lnetcdff -lblas -llapack </append></SLIBS>
In the config_machines.xml file, I added a configuration for my local machine named "mygnu", with details provided in the attachment.

After successfully running:./create_newcase --case testMEX --compset I1PtClm50SpGs --res 1x1_mexicocityMEX --machine mygnu --run-unsupported./case.setupand./case.build
I executed ./case.submit, but encountered an error. The error log is included in the attachment named "error".
