Describe the Bug

Facebook login function crashes when tapping the button responsible for the signInWithFacebook() function. It crashes right before FacebookAuth.instance. It seems to fail to get an instance on iOS. Same function is used on Android and it is working fine. iOS simulator is on iOS 16.4

Expected Behavior

Redirect to browser to proceed with login.

To Reproduce

No clear ways to reproduce. It was working fine up until very recently. Facebook app is set up correctly. Firebase is set up correctly. It just crashes without giving ant information inside the IDE. I can only see through the log output.
