2018.4.15f1 notes this bug.
iOS: Fixed AVCaptureSession initialized if permission to camera has been explicitly denied by the user.
I have not tested yet, but that should fix your issue if you come across this.

Unity 2019.2.13f1 is your latest, non-beta release. Can you please ensure it's working on both iOS and the mac editor (2018 and 2019)?

Still happens on 2018.4.12f1
Major issue for us!
We also found on the Mac editor, if you deny the permission field, and follow the same steps (close/new boot up), it freezes to the point the editor can't even be force closed. A restart is REQUIRED.
When fixing in 2018 can you please also fix it so the editor while testing will not crash. Thanks!

We're seeing this issue as well in 2018.4.10f1. Is Unity looking into this issue still?

This still happens in Unity 2019.2.2f1
Can confirm it is fixed in 2019.3.0b4.
Haven't tried other versions currently.
As aside note, Unity 2018.2.6 doesn't even need to request permission for Webcamtexture.devices for iOS. Can't seem to find info on why this was changed?
