      Environment:

      MacOS 15.6 / MacBook Pro M4

      Qt Creator 18.0.0-beta1 (17.0.82)

Built on Jul 29 2025 01:45:10 based on Qt 6.9.2 (Clang 15.0 (Apple), arm64)

From revision 3799891ee6

       

      Steps to reproduce:

      1. Open any example PySide project in Qt Creator.
      2. While project configuration window appears, select Python kit that has two configurations and select both. 
      3. Click Configure project button

      Expected: The app should not crash, and the project should be configured for both build configurations. 

      Actual: The app crashes immediately after clicking the button. See the video. I attached also the log. 

       

      Reproducibility:  100%
