Our app has been getting these types of crashes since the 3.12.0 that required a view controller as an initialization argument for IMAAdDisplayContainer. I was able to reproduce this crash in the Basic Example app that is part of https://github.com/googleads/googleads-ima-ios-dai.
This was done using the example app and on a iPhone XS Max with Xcode 12.4. I stared the app and then played the video. I would then start instruments to monitor memory allocations. Eventually the app would crash with this error.
Fatal Exception: UIViewControllerHierarchyInconsistency
A view can only be associated with at most one view controller at a time! View <IMAWKWebView: 0x120a28b40; frame = (0 0; 414 233); opaque = NO; autoresize = W+H; layer = <CALayer: 0x2802e81c0>> is associated with <IMAWebUIViewController: 0x10b7b9a90>. Clear this association before associating this view with <IMAWebUIViewController: 0x10b4471c0>.
I have also added the partial crash log below

Hi Eric,
Thank you for raising this to us.
With regard to your concern, I could see that you're using a SDK version which is quite old. Would it be possible for you to upgrade to the latest version of the SDK, then let me know if you still encounter the crash?

Hi Eric,
Do you see this happening without monitoring? Would a user of an app experience this crash? I ran the Basic Example app with SDK version 3.14.3 in Xcode 12.5 with Profiler recording in an Iphone 8 plus and this crash didn't occur.

Hi Eric,
To reiterate what Aryeh asked, do you see this happening without monitoring? How do you exactly do and implement monitoring? For us to investigate further, could you please send us a sample project file implementation along with the screen recording of the behavior?

The only way I have been able to reproduce this error is with instruments running watching memory allocations. However, I have had testers report this crash through testflight. In addition our crashlytics shows this crash occurring in production builds. I have created a recording of reproducing the crash and have sent it to imate...@gmail.com

Hi Eric,
Thank you for the additional information.Seeing as how we have not been able to replicate this on our side with the basic sample app. Along with the fact that yiu have been using other applications to track this behavior makes it difficult to find what the issue is. If you can share with us your sample app for us to test with we can try to look further into this. Also we would suggest to test without any extra add ons as they could be causing the issue. The other thing that we need to look into is why the error is saying that you are using more the one UIController. We would need to make sure that there is not more than one in use at a given time.
Also as a side note to this, one of the other things I have seen is that to make sure if you were using code from another section and reusing it in the same spot as the ad, that you might have mistakenly brought in another ViewController.
