macOS 15.7.1

Steps: 

1. Open the app and go to Examples tab.
2. Select any example and configure it against any kit (I used macOS kit) 
3. Select Kit Configuration and change the CMake version used. 
4. Go to Manage Kits and go to CMake tab.
5. Change the CMake version and click OK.

Expected: CMake version is selected - no crash.

Actual: The app crashes on pressing the OK button. See the attached recording on what it looks like.
