PMIx v4 support has been temporarily dropped in Slurm : https://github.com/SchedMD/slurm/commit/34bd96a

As far as I can understand, it has never worked properly due to some changes in PMIx starting from v4. There is an ongoing effort to fix this:

Maybe you can try this Slurm fork where work is being done:
