I have recently started to get stability issues (crashes) reported when uploading my Xamarin app to the Google Play Console. Below is a sample stack trace:

Exception java.lang.IllegalArgumentException: View=DecorView@3961ac5[] not attached to window manager

Unfortunately, I have not been able to reproduce this issue, nor has it ever turned up in my user crash logs. Can anyone suggest where I might start looking for the cause?
