Hi all,  
I’m using `mne_gui_addons.locate_ieeg` to mark iEEG electrodes manually on a CT coregistered to an MRI (FreeSurfer) on macOS 15.5 (Apple Silicon, arm64).

The GUI starts correctly, and I can mark the **first electrode** with no issue. However, right after marking the **second electrode** , the program crashes silently — no traceback, just a sudden termination. This happens consistently, both when running via VSCode and via terminal.

In one case, I traced the crash to the following error:

css

```python
TypeError: _PyVistaRenderer.set_camera() got an unexpected keyword argument 'reset_camera'

```

This suggests an incompatibility between `mne_gui_addons` and either `pyvista` or `pyvistaqt`, possibly specific to Apple Silicon. I tried multiple combinations of versions and environments.

Here is my environment summary from `mne.sys_info()`:

diff

```python
Platform macOS-15.5-arm64-arm-64bit
Python 3.11.9 | packaged by conda-forge
CPU Apple M4 Pro (14 cores)

Core
- mne 1.9.0
- numpy 1.26.4
- scipy 1.15.2
- matplotlib 3.10.1 (backend=QtAgg)

Numerical
- sklearn 1.6.1
- numba 0.59.1
- nibabel 5.3.2
- nilearn 0.11.1
- dipy 1.11.0
- openmeeg 2.5.6
- pandas 2.2.3
- h5io 0.2.5
- h5py 3.8.0

Visualization
- pyvista 0.45.0
- pyvistaqt 0.11.2
- vtk 9.2.6
- qtpy 2.4.3 (PyQt5=5.15.8)
- mne-qt-browser 0.7.1

Other
- Apple Silicon (arm64), no Rosetta
- Using conda (conda-forge) to manage dependencies
- Tried also on Python 3.10 with same behavior

```

Any advice on known compatible combinations or workarounds would be appreciated. Thank you!
