macOS: v1.1.1 seems not to support Apple Silicon M5 on MacBook Air

### Problem description

Fantastic software - Thank you - but it seems not to support Apple Silicon M5 on MacBook Air yet - FreeCad 1.1.1 crashes every time I try to make even simple operation on my MacBook - whereas it is running quite stable on my Windows machine. It's a brand new MacBook Air M5 running macOS Tahoe 26.4.1 and FreeCad 1.1.1 was the first app I installed. It crashes after a few seconds in Part and PartDesign after a few operations - it also crashes in safe mode. I get some strange notifications (**invalid index ....**) - Please see attached screendump

### Workbench affected?

Part

### Steps to reproduce

Not possible to attach zip due to crash

### Expected behavior

running without crashes 😊

### Actual behavior

FreeCad 1.1.1 crashes after a few seconds and very few operations - seen in Part and PartDesign. It also crashes in safe mode and also with the OpenGL option checked. Please see attached screendumps

### Development version About Info (in Safe Mode)

```shell
Not tried yet - but I will
```

### Last known good version (optional)

```shell

```

Start by reproducing the crash in the Part and PartDesign workbenches on the reported Apple Silicon MacBook Air, comparing normal mode, safe mode, and the OpenGL option. Collect the development-version About Info and crash details, then identify the failing area; done means the affected operations run without crashes on macOS.
