How to catch the error "Invalid rank, error stack"

Hello, when I use the following code to convert the gmsh model to mesh,

mesh, subdomains, boundaries = dolfinx.io.gmshio.model_to_mesh(model, comm=mpi4py.MPI.COMM_WORLD, rank=0, gdim=2)

sometimes it will occur the following error and the program is terminated.

Invalid rank, error stack:
internal_Issend(60788): MPI_Issend(buf=0x55d4dfb364b1, count=1, MPI_BYTE, 1, 1, comm=0x84000003, request=0x55d4df9eff74) failed
internal_Issend(60749): Invalid rank has value 1 but must be nonnegative and less than 1
Abort(674890502) on node 0 (rank 0 in comm 416): application called MPI_Abort(comm=0x84000003, 674890502) - process 0

Is there any way to catch the error, and I can ignore this case so that the program will not break due to this error?

Or is there another way to avoid this type of error?
