Hi,
The crash is caused by a bug in the app “Android System WebView”. The bug makes several different apps crash, including AntennaPod. Google has already released a bug fix update. Have a look at the Play Store to see if you are running the latest version of “Android System WebView”.
If you don’t see the update yet, you can also try uninstalling the updates of that system app. In the long run, you want to use an up-to-date version of that app, though.
