Steps to reproduce:
1. Open the “Attached project”
2. Make sure the Inspector window is open and select “InputSystem_Actions” through the Project Window
3. Go to “Windows/Text/FontAssetCreator” through the Main Menu
4. Select “SoeiReishotai” as the Source Font and “Japanese-Lipsum” for the Character File
5. Click on “Generate Font Atlas”
6. Observe the crash or the font being generated with another font instead of SoeiReishotai

Reproducible with versions: 6000.0.64f1, 6000.3.1f1, 6000.4.0b1, 6000.5.0a3
Couldn’t test with versions: 2023.1.0a26 (Glyphs get stuck while generating)

Reproducible on: macOS 15.7.2 (M1 Max)
Not reproducible on: no other environment tested

Notes:
- The crash is inconsistent
- Freshly extracting the project before reproduction gives a more consistent crash
- If no crash occurs, closing the Editor will make Unity unresponsive
