Fatal Exception: java.lang.NullPointerException Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

[Timo]

My app is crashing for a significant part of my users since about a month, without me pushing any update. I am using the latest AdMob SDK 24.4.0, but it also happened with AdMob-Lite 24.0.0

I am using collapsible banner ads and cannot reproduce it locally on my devices.

There's a related post here, which I don't seem to be able to add my comment to: https://groups.google.com/g/google-admob-ads-sdk/c/8v1AaXj_2EM

I see two slightly different stack traces:
