Hi Team CameraX,

Gradle version 8.5.1 seems to currently causing a crash (possibly due to minification) for CameraX extension usage. One of our users reported that switching to night mode caused the preview to freeze and switching to another mode (which rebinds a new camera instance) caused the preview to unfreeze.

Quoting their report on this issue,

After updating to v69, switching to Night mode (on a Pixel 6, but likely not specific to just this model), the preview frame freezes. Switching to another mode unfreezes it.

If you press the button to take a photo regardless, nothing happens, but when you try to switch to another mode after that, you get an error, with the following log:

Downgrading to Gradle 8.5.0 in our app's recent release caused the issue to no longer persist. Could you'll please help us fix this issue?

The CameraX version for which we're facing this issue is CameraX 1.4.0-beta01 and the device on which this issue was reported is Pixel 6.

Please do let us know if any additional information is required for the same

Thanks a lot for your time and all the help and support!

Regards,

Mohit
