My Xcode version: Version 16.2 (16C5032a)

I tried upgrade my IPad Air from 18.4.1 to 18.5 (22F76). the Error still here. Here is the error from Xcode, hope can show the problem.

I tried using the iPad Pro gen 4th, with IPadOS 18.3.2, it would not have the same problem.

Hello @livtechhk,

Thanks, but those files are not the full crash log. See Create a crash report while debugging for instructions on how you can get a crash log.

is the .ips file is enough or not ? https://drive.google.com/drive/folders/1i7-uNajMh3CFTCDN-PqPBuKV__r2BoQ8?usp=sharing

Hello @livtechhk,

The .ips file is enough. According to your logs, this crash is due to an invalid memory fetch.

I recommend that you follow the investigation steps detailed in Investigating memory access crashes.
