      Since the update to Qt 6.9.1 we are encountering a crash on iOS with VoiceOver enabled. A screenshot of the crash dump is attached.

      Please find attached MWE and steps to reproduce:

      1. Enable VoiceOver
      2. Start MWE
      3. Push new page
      4. Pop page
      5. Application crashes in QAccessibleCache::removeAccessibleElement

      I had a look at the file's history and assume that https://codereview.qt-project.org/c/qt/qtbase/+/632596 is causing this crash. 

      [element release];

      seems to be the issue here.

      Oddly enough the same crash does not occurr on macOS even though it's the same code.
