### 🐞 Description of the bug

https://mechanical.docs.pyansys.com/version/stable/examples/gallery_examples/01_basic/cooling_holes_thermal_analysis.html

I am running the same example.

However, it gets stuck when I try to save the image. If I comment out the image extraction, the full script works fine, so the issue seems to be with saving the image.

### 📝 Steps to reproduce

https://mechanical.docs.pyansys.com/version/stable/examples/gallery_examples/01_basic/cooling_holes_thermal_analysis.html

### 💻 Which operating system are you using?

Linux

### 📀 Which ANSYS version are you using?

2025R2

### 🐍 Which Python version are you using?

3.11

### 📦 Installed packages

```shell
All using ansys python manager (latest), Today installed.
```

Start by running the linked cooling-holes thermal analysis example on Linux with the stated Ansys 2025R2 and Python 3.11 environment, then isolate the image extraction and saving step. Compare the run with image extraction disabled and collect the point where saving hangs. Done means the example completes and saves its image at the requested location.
