The reason is that your own +initialize method called, the original +[NSString initialize] method never be invoked once.

Use dsc_extractor to extract the Foundation.framework out from the dyld_shared_cache_arm64, that pull down from iOS 15.6 (on $HOME/Library/Developer/Xcode/iOS\ DeviceSupport/15.6/Symbols/System/Library/Caches/com.apple.dyld/dyld_shared_cache_arm64e).
Drag it to Foundation.framework/Foundation to IDA64.
So, the reason is obvious, the +[NSString initialize] will enable/disable the NSTaggedPointerString feature. If u implement one in category, your app will not recognize a Tagged Pointer String.

Using a UITouch Category to Override this method and check the Deallocating object. - (BOOL)_wantsForwardingFromResponder: toNextResponder: withEvent:
How to use? Just drag the ObjcUtil.h/m and UITouch+FixCrashOnInputKeyboard.h/m into your Xcode project, and done.
Look at this,hope it helps you - https://developer.apple.com/forums/thread/711820?answerId=745458022#745458022
