iOS Crash : JobQueue::WaitForJobGroupID(JobGroupID, JobQueue::JobQueueWorkStealMode)

[oguzfrsk]

Hello,
Recently, we upgraded our Unity version from 2021.3.11 to 2021.3.27, and we started experiencing significant crashes on iOS. The crash-free rate dropped from 99.5% to 93%. Our project includes Adjust, GameAnalytics, FacebookSDK, Firebase, and ApplovinMax plugins. In the latest update, we only updated Unity and a few mediation networks within ApplovinMax. I’m also sharing the stack trace (also attached a txt file)
We are not sure if this issue is related to the Unity version, as we have been unable to reproduce it on our own devices.
