Hi! @DTS Engineer Thank you for your prompt response and guidance. I have uploaded the minimal Xcode project ZIP and the symbolicated backtrace to Feedback Assistant report FB24985530.

I’m attaching additional diagnostic information: the backtrace captured at the point where the Objective-C exception is thrown, and the full crash report from a separate reproduction without the debugger attached. JP_Kana-Keyboard_Symbolicated-Backtrace.txt

I was able to reproduce the issue with this sample code in both environments. Xcode 16.0 (16A242d), iOS 18.0 simulator Xcode 16.1 beta (16B5001e), iOS 18.1 simulator

I'm also having the same problem.

I'm having the same problem. Is there any solution?
