Hi,
We ran the Google sample project using your app ID, ad unit ID, and Mobile Ads SDK version 23.3.0, but we were unable to reproduce the crash. Could you try running our Google sample project on your end to see if you can replicate the issue and share the results with us?
We also recommend keeping your SDKs up to date, and the latest version as of today is 23.5.0. Please refer to the Google Mobile Ads SDK release notes for further details.
If the issue still persists, kindly provide us with the below information for further investigation privately:
