      I updated just one app from Qt 6.7.3 to Qt 6.10 and I have seen a lot of these crashes.

      Regardless if I use native plugin or the ffmpeg plugin the crash is still present.

      In my app I use QML SoundEffect-s to play wavs and MediaPlayer to play mp3s for background music. Thus I am not doing anything fancy in my app.
