Critical errors: 0x00000004 after update 15.7.0 -> 16.0.0

[fm-maniac]

The Problem

After updating from 15.7.0 to 16.0.0 the system reported:

We have one or more critical errors: 0x00000004

Which seems to be an issue with the camera.

After downgrading to 15.7.0 the system returns to proper operation.

What went wrong?

Version

16.0.0

On the 2nd attempt the update to 16.0.0 passed through. Don't know what causes this issue on the first run.
