I have checked on various platforms for this issue. But have not found any solution related to it.Please provide any solution related to it.
It is crashing on app launch itself and this is the report it shows on fabric
I've the same issue on iOS 13 and it's my most serious crash on Crashlytics. It occurs only in iOS 13 and above. Unfortunately also in the latest 13.1.2.
Starting by the iOS 13 release I've detected a strange warning when I put my app in background the debug console print Can't end BackgroundTask: no background task exists with identifier x, or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
Maybe the issues are related.
