[Bug]: Once set up biometric, app crashes

[JeanlChristophe]

Describe the bug

Once set up biometric, the screen is all black, nothing works anymore. Even after forcing close the application 10 times, I still have a black screen.

It already happened to a user earlier : https://app.asana.com/0/1203624355958644/1204377573367004/f

Reproduce

1. Go to 'Settings'
2. Click on 'Security and 'privacy'
3. Click on 'Use biometrics instead'
4. See error

@JeanlChristophe Can you please post a recording of this bug? Do you have a fingerprint setup on your phone?

[JeanlChristophe]

I no longer have access to the profile with which I had the bug.
And with a new profile, I can't reproduce the error. It happens from time to time, but rarely.

From support, we have a user having a issue:

"I have activated biometrics authentication, but it crashes the app every time I log in.
Recently, it started working again (no crash after logging in) but that was only temporarily, and the problem started again.

Restoring on another device did not work. It's stuck here. See attached sorry clip"

@JeanlChristophe

I need more information here as I cannot reproduce this issue on my phone and am flying completely blind.

• When does the crash occur? Immediately after enabling biometrics? Only when starting the app?
• Which biometric method are you trying to setup? Fingerprint or face recognition?
• Does the screen just stay black or does the app crash? Is there an error screen/message?
• Please provide a screen recording of the issue

Please answer above questions thoroughly, with any luck this will be fixed with https://github.com/synonymdev/bitkit/pull/1110
