Description
Observing this when analyzing our users' crashes in Sentry.
It's never reproduced in our testing environment, but seems this may happen when user connect/disconnect headphones during media playback.
Some helper AVF thread is crashing:

There is nothing specific in the app code, we just use QML MediaPlayer to play user's media files.
Something like:
VideoOutput {
id: output
...
}
MediaPlayer {
videoOutput: output
audioOutput: AudioOutput { device: <some_binding_to_device> }
source: <some_binding_to_source>
...
}
