I search for a few days but have no idea.
Environment:
Unity 5.6.4p1
Xcode 11.3
il2cpp
Devices:
iPhone 6
iPhone 6s
iPhone 6p
iPhone 7
iPad 5
iPad 6
also a little parts on iPhone XS、XS Max
iOS version:
9-13.x
I can't reproduce on local device, so can't confirm wether it's fixed.
Hope someone can help.
This looks like a bug (DISABLING UI CRASHES AT GAMEOBJECT::ISACTIVE), try to upgrade Unity to the latest stable version.

We encountered an OpenGL related crash on ios14. It has nothing to do with the application background. The vast majority of crashes occurred on IOS 14 low-end devices, and it is not clear how to solve them.
The only possible clue is that the crash may have something to do with opening the WebView.

I'm 100% sure presentRenderBuffer works fine in iOS14.
According to the error message, it seems like a thread issue.
In my case, I use a queue to detail with all of the OpenGL things.
dispatch_sync(queue, ^{
// All of the OpenGL things
[self bindCurrentRenderBuffer];
[self presentRenderBuffer];
});
You can see my OpenGL project in Github: IRPlayer
I am unable to reproduce the issue. One of my user sent the crash log and the issue seem to point to NSUserDefault setBool:forKey method.
Not working for user Device iPhone 6, iOS version: 12.4.4. For now only one user contacted due to the App crash.
Working on the devices I tested. (iPad Air 2, iPhone XS, iOS version 13.3)
This is the method I am using.
- (void) saveToDefaults:(NSString*)productId
{
[ [ NSUserDefaults standardUserDefaults ] setBool:YES forKey:productId ];
[ [ NSUserDefaults standardUserDefaults ] synchronize];
}

How can I handle this exception to avoid this problem in the future.
Following up comments discussion and this answer indicating synchronize is not required (as per Apple's iOS 12 release notes):
My target iOS is from 11.2, guess I cannot use it for now.
Yes you can.
Wrapping up my suggestion in comment :
if (#available(iOS 12, *)) {
// don't need to synchronize
} else {
[NSUserDefaults.standardUserDefaults synchronize];
}
The above code #available Swift-like syntax assumes you're using Xcode 9 or higher. Which given the targeted iOS is pretty much a must.
Just to make myself 100% clear I cannot guarantee this will solve this particular crash issue, but it is worth trying as a very low effort fix candidate.
As iOS13 release, there are more and more mapKit VectorKit crashes on the app which we are working on. We can not reproduce the crash internally and there are over 200 crashes collected by our own crash reporter everyday.
From all the information we have got, the crash always happens when the application come to active from background, and at that time, the ViewController view has a MKMapView subview. Maybe something wrong when the system rendering the map UI.
This problem seems a long-lasting iOS problem since iOS11 or even earlier. Now, The crash related iOS13 system version includes 13.0, 13.1, 13.1.1, 13.1.2. I have reported the problem on the Apple bug report system, but no any response from Apple until now.
Any advice or hint will be greatly appreciated.
FYI. The crash stack as below.

Check your CPU utilization on iOS12 vs iOS13.
I noticed that my app was crashing because I was adding and removing polylines to the map too frequently (although this problem only manifested in iOS13, not iOS12).
See my SO post about this here.
Look at your crash logs and see if you spot something like this:
Event: cpu usage
Action taken: Process killed
CPU: 48 seconds cpu time over 54 seconds (88% cpu average), exceeding limit of 80% cpu over 60 seconds
CPU limit: 48s
Limit duration: 60s
CPU used: 48s
Duration: 54.45s
Steps: 15
My app stopped crashing in iOS13 if I reduced the frequency for redrawing the map overlays.
Here is the crash report and the crash is only happening on iOS 13 beta version :-

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.
We ported our app from UIWebView to WkWebView.
Since then the app crashes sporadically (sometimes after minutes, sometimes after hours, sometimes not at all) while being in background.
Looking at the termination reason 0x8badf00d (see crash report below) and Apple's developer documentation (Understanding and Analyzing Application Crash Reports) the crash seems to be related to a watchdog timeout.
The only task we start in our code while the app moves to background is embedded in appropriate calls to UIApplication.SharedApplication.BeginBackgroundTask and UIApplication.SharedApplication.EndBackgroundTask. That task is a network request that does not run on the main UI thread and it completes within a second.
That said I assume the crash to be related to a WebKit / JavaScriptCore issue.
Did anyone else experience such crashes (exception type EXC_BAD_ACCESS (SIGKILL) & termination reason Namespace ASSERTIOND, Code 0x8badf00d) and can provide any specific hint about how to avoid them?
Many thanks in advance & best regards!
Mario.
