When I try to open the result from my simulation from Ansys 2023R2 my kernel crashes :
But when I try to open result from another simulation from a previous version one it works.

### 📝 Steps to reproduce

Try to open a .rst file from an Ansys 2023R2 simulation,

### 💻 Which operating system are you using?

Windows

### 📀 Which ANSYS version are you using?

Ansys 2023R2

3.10

### 📦 Installed packages

```shell
pip install ansys-mapdl-core
```

Start by reproducing the crash with an Ansys 2023R2 .rst result on Windows using Python 3.10 and compare it with a result from an earlier Ansys version. The issue is complete when the 2023R2 result can be opened without crashing the kernel, with the relevant failure identified and covered by a regression test if the project provides one.
