🐞 Description of the bug

Hello!
I'm having difficulties trying to run the block model example. It seems i'm unable to load the CAD with mesh_util read.

https://prime.docs.pyansys.com/version/stable/examples/gallery_examples/gallery/00_lucid_file_IO.html#sphx-glr-examples-gallery-examples-gallery-00-lucid-file-io-py

I'm currently using py3.11.9 in a virtual environment, with ansys 2024R2 and py prime mesh 0.6.2. I'm on windows10.0.19045 pro.
I used the ProductConfig.exe script in the ansys files to configure CAD readers, and i can successfully read the example in SpaceClaim.

I tried investigating, and i launched the prime server without the launch_prime() function (using a cmd, calling the runPrime.bat) and i noticed the server correctly booting, but as soon as i run the example script on Python, trying to connect to the server and read the geometry; the server crashes saying "the DLL load failed while importing PyFM: the OS cannot execute %1". As soon as this error arises on the server prompt, i get the import CAD failed error in my python script.
I also encountered the same problem with some of my coworkers.
Do you have, by any chance, any idea where this could be coming from? Thank you very much

📝 Steps to reproduce

1. First in a cmd prompt: "%AWP_ROOT242%\meshing\Prime\runPrime.bat" server

which shows:
C:\Users\Guillaume>"%AWP_ROOT242%\meshing\Prime\runPrime.bat" server

Copyright 1987 - 2024 ANSYS,Inc. All Rights Reserved.
Starting Ansys Prime Server...
Server listening on : 127.0.0.1:50055

2. then i try running with python:
   import ansys.meshing.prime as prime

prime_client = prime.Client(ip="127.0.0.1", port=50055)
model = prime_client.model
mesh_util = prime.lucid.Mesh(model=model)

mesh_util.read(file_name="D:\MEC8370\PyPrimeMesh\test PyPrimeMesh 3\pyprime_block_import.scdoc")

print(model)

3. On the cmd prompt i used to launch the prime server, the error arises:
   C:\Users\Guillaume>"%AWP_ROOT242%\meshing\Prime\runPrime.bat" server

   (which is french for "the OS cannot execute %1)

4. The python scripts immediately crashes afterwards, with this error:
