I have such a problem, I put together a build for ios in unity.
When I run a app:
-IOS 14+ and IOS 13.6 starts up and works
-IOS 12.3.1 and IOS 13.2 crashes when start
The application opens, freezes and crashes.

Know someone who can answer?
Those are system components. Generally, you should only go into those folders when you have a reason to do so.
When you run the second command, the change is being made to the root account's settings and not those for your normal account.

My app is working well and I didn't get this error on Xcode 13.4,
Is it Xcode 14 beta bug or I'm doing some bad threading?!

I didn't understand the issue, so I added my stack log too:

You're getting this message due to a priority inversion in your code. More details here: https://developer.apple.com/documentation/xcode/diagnosing-performance-issues-early
More specifically, you're using dispatch_group_wait which doesn't provide priority inversion avoidance; so your waiting thread is susceptible to an inversion. Seemingly that's what's happening here.
There are a number of crashes being reported on Crashlytics (Fabric.io) for my app which is live (in Production). I (and my few of my friends) also use the same app regularly but have never seen any crash.
In detail- As per the crashlytics dashboard, the crash is caused in a Framework (also developed by me but cannot add crashytlics there - reference this) and the logs have below details -

Also, whenever I get this crash, I see below in my report -
The screenshot says, there is a Fatal error while trying to unwrapping a nil value. And I see some strange characters like question marks.
Putting these things together, I assume I am getting an error in my Framework ViewController file (QRUIViewController in the logs) but I am not unwrapping any nil value in my whole code in that file.
Can anyone please help me understand what is going on with the app?

Tons of crashes start happening on iOS 11 in the apps using UIWebView and showing rich content, like ads or videos. It was a similar problem in 2015, which then was fixed (see here). Now it re-appears again.
I saw some similar, but I still decided to post my problem, this is not a duplicate, but aggregated information about this crash from different, seems not-related at glance sources. Hope it will help to bring attention and solve the case faster. I also want to give bounty on the solution, so please don't remove this question.
My case - UIWebView in native Obj-C app. The problem only appears to happens in free version, which serves the ads. The date when it starts - July, 22. It was no app update at the time. All crashes in iOS 11 only. Thousands of them. Crash stack:

React Native IOS 11.3 - 11.4 Error: JavaScriptCore JSC::JSLock::DropAllLocks::DropAllLocks. It seems that embedded Video Widget causes the same problem, also only iOS 11. The React Native platform seems unrelated, because the problem happens also in native Obj-C apps.
Javascript core crash when using YouTube iframe player in UIWebView in iOS 11.3. YouTube iframe player causes the same problem. Again, all starts iOS 11.
This is huge problem, please advise and help us solve this. Thanks!

I've read some subjects about errors like this one. Each time, people says that comes from Permissions in infos.plist.
App uses camera, library, geolocation. So I add :
Privacy - Camera Usage Description
Privacy - Location When in Use
Privacy - Photo Library Usage Description
But there is always the same problem.
I add Microphone usage in plist, but same crash occurs.
I don't understand the crash. On my iPhone, everything works perfectly but on some devices, this error cause crashes. Could you help me please ?
Thanks.
Check all of your WKWebView that is are loading images.
If you long press on Webview it shows an option to save photos in app.
Fix for the crash:
webView?.allowsLinkPreview = false
This is the crash report I received from crashlytics and I don't have the slightest clue on what it means or what to do about this. Any tips or suggestions will be appreciated.

Do you have any part of your app where the user clicks on a URL or specifies a URL which is then handled by your app, or by the system on behalf of your app. The subsystem that does this is DataDetectorsCore.
If you have code around that area, it would be a good idea to add log messages, assert checks, validation, and unit test code.
It might be that you are receiving maliciously crafted URLs; here is an example but for the Mac platform: http://nakedsecurity.sophos.com/2013/02/06/anatomy-of-a-bug-how-mac-os-x-chokes-if-you-type-file/
