<![CDATA[Qt Creator crash on macOS when editing UI file in the designer]]>Running Qt Creator 18.0.1 Built on Dec 9 2025 12:41:52 based on Qt 6.10.1 (Clang 15.0 (Apple), arm64).
I was editing the serial port example and had duplicated the serial port settings part of the dialog to allow the use of 2 serial ports.

I was renaming the UI elements in the inspector:

During the selection and renaming of the UI elements Qt Creator crashed with the following stack trace. Has anyone encountered this, it's happened several times for me but I can't pin it down to one particular action.
