Bug on iOS 14.4 (18D52) with Vision on iPhone SE (2nd gen)

Hello,

I found a bug using Vision for face detection on iPhone SE second generation.
When I execute the Apple demo project for face detection (https://developer.apple.com/documentation/vision/tracking_the_user_s_face_in_real_time) I have no face detected and the following error logs :

This bug is very annoying because it brokes all apps using Vision at least on this iPhone and iOS version.

I have an app using this technology on the AppStore, that's how I firstly discover the problem and am hopping for a quick fix.

iOS version : 14.4 (18D52)
iPhone SE second generation
Xcode version 12.4 (12D4e)

Edit : this seem to be solved with iOS 14.4.2.
Can we have more information about this bug ? Is it device model relative or all device with iOS 14.4 will have this bug ?
