Steps to reproduce

We are using FBAudienceNetwork (6.12.0) to display ads within the app. The FBAudienceNetwork is installed as a dependency to AppLovinSDK and AppLovinMediationFacebookAdapter which we are using to load ads.

The crash happens randomly on other test devices, but more often on a user (iPhone 12 Pro, iOS 16.2). Can't say how many users are affected in the release because it is not logged to Firebase Crashlytics.
We notice that It occurs while the app is in the background for 2-5 minutes.

This crash is not recorded by Firebase Crashlytics or Xcdore crash report, we noticed this when investigating crash logs the device which happens very often.

Code samples & details

We don't know what code leads to this crash.

[mahaghanemamer]

same problem here :(

[gonsee]

Same here.
We see hang logs in the Xcode's organizer.
There seems to be a deadlock issue with thread 16 in the crash log provided in this issue's description.

[gonsee]

A work around suggestion.

hello, did you find anything on this?
We are experiencing same issue now.

[su855297]

We finally resolved it using this method

replace FBSDKAppEventsDeviceInfo with our custom function encodedDeviceInfo.

Hello @su855297 thanks for response.

I want to ask how do you imported FBSDKAppEventsDeviceInfo class?
It keeps giving me Use of undeclared identifier 'FBSDKAppEventsDeviceInfo'

[su855297]

try it.
