HDF5 read failure in hdf_archive::read /format (QMCPack 3.17.1, cray-hdf)

**Describe the bug**

I ran a simple PBE calculation in ORCA (cc-pVDZ basis), converted the .gbw file to molden using orca_2mkl, and then used molden2qmc to convert it into an .h5. I then generated a simple QMCPack input which is supposed to optimize the Jastrows.
The script crashes when it's reading the .h5 file -- any idea why?

```
HDF5 read failure in hdf_archive::read /format
Fatal Error. Aborting at Unhandled Exception
MPICH ERROR [Rank 0] [job id 4614716.0] [Tue Sep 26 17:33:00 2023] [nid005005] - Abort(1) (rank 0 in comm 0): application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
```

I've attached the molden file, job script, input .xml, and converted .h5. The same happens when I use a different basis, or use the .gbw from a CCSD(T) calculation ... I'm expecting it to be something very stupid (like that the .h5 is empty or has the completely wrong format). I've appended the directory structure of the .h5 as well for convenience.

**To Reproduce**
Steps to reproduce the behavior:
1. execute the attached .xml

**System:**
- LUMI; the build passed all deterministic tests.
- modules:
```
module load LUMI/22.12
module load partition/G
module load buildtools
module load cray-fftw
module load cray-hdf5-parallel
module load libxml2/2.9.14-cpeAMD-22.12
module load Boost/1.81.0-cpeAMD-22.12
```
