The app runs completely fine when I debug it on an IOS simulator. But when I upload it to testflight and the app store it often crashes the first time I open the app after I have closed it for a while.
I get the crash when it still runs in the background but I don’t have the open open for at least 10 minutes.

I have build a Xamarin.Ios app with the following Nuget packages:

-Acr.UserDialogs
-MySqlConnector
-Plugin.AudioRecorder
-Syncfusion
-TextCopy
-Xam.Plugins.Forms.KeyboardOverlap
-Xam.Plugin.Settings
-Xamarin.CommunityToolkit
-Xamarin.IQKeyboardManager

here is the IOS crash report:

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Termination Reason: SIGNAL 6 Abort trap: 6
Terminating Process: OnderdelenTest.iOS [964]
