It would help if you were more specific about what the system you are
trying to simulate is (are you e.g. trying to use the TIP4P water
model?) and what specific steps you've taken to try and solve the
problem. If your topology has any extra points it will not run using
pmemd.cuda.MPI. If you're not supposed to have any extra points in
your topology, it's possible something strange is going on. If you
would like, send me your topology (off-list) and I will look it over.

Make sure you see this in your output:

|--------------------- INFORMATION ----------------------
| GPU (CUDA) Version of PMEMD in use: NVIDIA GPU IN USE.
| Version 12.3.1

If the version number is any lower you don't have the most recent bugfixes.
