Where the following apis have been used, the operation has crashed UIGraphicsBeginImageContext UIGraphicsBeginImageContextWithOptions UIGraphicsGetImageFromCurrentImageContext UIGraphicsEndImageContext
The run crashed
Looking at the api documentation, it is recommended to use UIGraphicsImageRenderer instead.
But the project uses too many places, and is confused by the Xcode15beta forced run crashed
Copy the code in your project to hooks default behavior
#import <dlfcn.h>
#import <UIKit/UIKit.h>

maybe can apple don't allow dlopen extra dynamic libraries , UIkitCore is Not extra framework
