Bug: "Scan QR" to sign, followed by denying camera permission, freezes application

[boston-wine]

Minor bug in the camera permissions request flow.

Device: MacBook Pro 2019
OS: Ventura 13.3.1
Application: Sparrow 1.8.0

I created a test transaction in Sparrow, to send from an air-gapped signer. I clicked "Scan QR" which enabled the green "camera" light on my laptop, and brought up the System Preferences request to allow Sparrow to access my camera.

When I denied the request, instead of Sparrow returning to the previous screen or showing an error message, the application froze, with the computer's camera light remaining on, for a minute or so, until the application force-quit. There were no unusual messages when I reopened Sparrow.

It seems like this bug only occurs the first time that the app requests camera access. On subsequent attempts to scan a QR, the correct "Error Scanning QR > Cannot execute task" error appears.

New (or particularly privacy-conscious) Sparrow users may be concerned when the application freezes with the camera indicator enabled, especially considering that they have denied the application access to the camera.
