My app works perfectly fine both in debug and release mode. But in Google play store vitals section there are 3000+ crashes reported within a weeks time with stacktrace as shown below. It looks like app is crashing in BroadcastReceiver on ActionBootCompleted, ActionDateChanged and ActionTimeChanged events. I am not able to understand this log so as to figure out the reason for so many crashes for almost every devices as reported in play store console. Kindly help.

So, you can go to google play for better help: https://support.google.com/googleplay/community?hl=en

2021-06-02T09:23:12.03+00:00 You have misunderstood me. Look, yes it works fine when run in debug or release mode via Visual Studio, but, once i have released update to my app last week too many (around 3000+) crash report has got generated, which are available in google play developer console's Vitals section. This means app is crashing because of unknown reason on many user devices. Kindly help.

What update did you make? Did these errors not occur before the update?

2021-06-04T03:02:11.827+00:00 I made many changes to my app, and then released update on play store. since then it is generating crash reports. No errors were reported before releasing the update.

2021-06-04T07:28:31.457+00:00 Is there a full log of above problem? Based on these logs alone, it is difficult to locate the problem.

2021-06-07T08:50:56.627+00:00 You can try to add a managed global exception handler, e.g.:
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException; static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs args) { Exception e = (Exception)args.ExceptionObject; System.Diagnostics.Debug.WriteLine($”{e.Message}\n{e.StackTrace}); }
