App crash on v16 - iOS 26

Has anyone else experienced this, I think our app is experiencing this due to a lot of preloading, as yet I haven't been able to create a repro, just wondering if anyone else has tested on iOS 26 with no issues

Basically seems like whenever a video component is removed from the view we get this crash:

Only happens in release builds, not debug.
