Over the last week, I've noticed a lot of -[UITableView _createPreparedCellForGlobalRow:withIndexPath:willDisplay:] + 1256 crashes on iPhone 14 Pro devices running iOS 16.1.1.
The tableView where this problem originates has a constant number of rows and sections, so the datasource is never modified.
The crashes are also being reported to Crashlytics and Sentry, but never make it into the Apple Organizer.
Any idea what's going on? How can I resolve this issue?

I discovered that there was a forced unwrapping deep inside my codebase. I would encourage you to search for any forced unwrapping.

let bottomOffset = bottomView.contentOffset.y
let currentOffset = overlayScrollView?.contentOffset.y ?? CGFloat(0)
let totalOffset = (bottomOffset + currentOffset) > 0 ? (bottomOffset + currentOffset) : 0
bottomView.contentOffset.y = 0
overlayScrollView?.contentOffset.y = totalOffset
I am facing several crashes of type EXC_BAD_ACCESS KERN_PROTECTION_FAILURE in app on this line
overlayScrollView?.contentOffset.y = totalOffset
Initially, I thought this is happening because KVO is not being handled properly, that might be message is being sent to deallocated object and observer is not removed.
Moved to new KVO keyPathBased APIs which removed overhead of removing observer. But still this issue is happening. This issue is not reproducible at all on my end.

I can not find out what the root cause it. Because _UIButtonBarStackView is mentioned I assume that it has something to do with a UINavigationBar UIBarButtons. It seems to happen when I dismiss a modally presented UINavigationController, but I am not sure.
It also looks like it started to happen with iOS 13.4.1, because I can't find any crash report with any older version.
Anyone might know what's going on here?
Found out the cause: I was adding the same UIBarButtonItem again to navigationItem.rightBarButtonItems. Apple seems to raise exceptions about that since iOS 13.4.1(-ish).
I seem to be getting this error after my new release and its only happening on iOS 13 with most cases of upto 83% of the crash happening on iOS 13.3.1. I am not sure how to fix this error and I have been going through the code and cannot seem to figure out the change in iOS 13 that causes scrollViewDidScroll delegate method to crash the app.
Any help is greatly appreciated. It is also important to note that I haven't been able to reproduce this error, it only happens to users in production.

I can not say a concrete answer unless you show a piece of code but there is a possibility that error might occur because of delegation structure. Just in case check your delegation of scrollviews(tableviews, collection views, embedded web-views as well). Please check the link link for more info.

I had the same problem and it was because of a UITextView in a storyboard and a critical issue in Xcode 11.2 fixed in Xcode 11.2.1 GM : https://developer.apple.com/documentation/xcode_release_notes/xcode_11_2_1_gm_seed_release_notes/
This update fixes a critical issue that could cause apps using UITextView to crash when run on previous versions of iOS, iPadOS, or tvOS. Please see the release notes.
Failed to load bounding path bitmap data from the asset manager for asset name: BoundingPathBitmap-1125x2436-375x812-3.00x
The crash happen on the viewcontroller contain UIScrollView When open it，and only happens with the iPhone X and above
We develop app UI use storyboard

hope someone could give me some advice, thanks
The same crash also happened in my app.
When I turned off the 'Show Horizontal Indicator' and 'Show Vertical Indicator' on the storyboard, the crash no longer occurred.
It just happened with my app .. Fixed ,
Delete the app and restart Simulator ..
