What's happening?

I've noticed an odd bug where when I build the app with:

• Xcode 26
• React Native 0.78+
• React Navigation 7.x+
• React Native Vision Camera v4.7.1
• CodeScanner property passed in
• Isolated on a straightforward app

Running on a real device, when navigating away, the app freezes for 5+ seconds, either on navigation or after navigating away.

Some notable things:

• CodeScanner property being passed in, this is reproducible 10/10 times, and freezes 5+ seconds
• CodeScanner property NOT passed in, this is reproducible 5/10 times, but the freezing is < 2 seconds
• When the Vision Camera is not rendered, the freeze does not occur

Video Demo

Can you reproduce this issue in the VisionCamera Example app?

UPDATE: I have tested with react navigation 6, and it is still freezing. so it may be related to the react-native version + Xcode 26

No, because the example app is using react native 75 and react navigation 6
