Hi @jacattrongnlh

This is a confusing bug, and I am not sold that Admob is the cause. That said, I understand it is frustrating and have seen this issue come up from time to time.

Could you try changing the Android API target API Level to 30?

[jacattrongnlh]

I replicated the bug on a build containing nothing but Admob, show an interstitial ad on it and it crashes. I can say with certainty that it's caused by Admob.

I have to target Android 31 to be able to publish on Google Play, do I have to lower the target API to 30 to avoid crashing?

[webmonch]

I also have a ton of similar errors after updating to the last admob on unity.

[kunny]

Since there were no recent activities for this issue, we are therefore reluctantly going to close this bug for now.

If you are still experiencing the problem, please file a new issue with the same description, what happens and system / network tracing / Charles logs.

All system setups can be slightly different, so it's always better to open new issues and reference the related ones. Thanks for your contribution.

[jacattrongnlh]

welp, responsible for thousands of crashes on my app and wontfix. I'll tell everyone to switch to other solutions.
